I'd leave her at home. I loved the beach as a teen. but dsis hated it. She burns very easily and feels the cold.
My parents didn't do the beach. They did lovely wonderful healthy long walks. I hated it. It wasn't good family time at all. My ideal of a nice day is not to set of at 9am with a bag full of still frozen squash and sandwiches and salad. At about midday stop in the middle of a muddy field with nowhere to sit down and discover they're still frozen. I usually deposited the sandwiches somewhere. Dp making comments on how wonderful it was to be out and aren't we glad we're not part of a boring family that might do something dreadful where you'd meet other people.
About 2pm check map. Find we're not where we expected to be. Df sets off at speed ahead of us. We trail behind through the short cut that should get us back to where he wanted to be. This involves cutting through a field of curious cows, a marshy plane which goes over everyone's wellies, and a farm which houses two aggressive dogs.
After a couple of wrong turnings we catch up with df. He's sitting down because he's heard a lesser tailed spotted whatsit and we wait 40 minutes while he tries to see it.
Continue on way, where he announces that actually he's decided it would be a good idea to see something else as we're so close so we have a 3 mile detour. Dm objects as she thinks it's far enough, and he informs us that actually it would have been a 3 mile detour, but we're already a mile and a half into it so it's too late to object.
We stop to admire the single stone which is what we detoured to see. Actually it's possibly not it, but we can't see it anywhere else, and this looks the most likely. No one has any energy to object.
We continue silent by this point as no one has any energy for talking. I now have a headache that's developing into a migraine due to dehydration (the squash still isn't properly defrosted and I'm not drinking anything more as I don't want to need the toilet).
Now we have a stoppage to admire a flower. No one can identify it and so a small sample of flower and leaf is carefully wrapped up to take home. It will be found three days later a brown mess, and the flower will be triumphantly identified as a garden escape. my family don't know garden flowers, only wild ones.
Then it starts to get dark. Df is again not quite certain where we are, but isn't admitting it. He's walking ahead again. We go round a corner and find he's disappeared. We don't know whether he's doing the terribly funny hiding trick or whether we've taken a wrong turning. He has the map and compass and we haven't a clue where we are.
After a short time dm decides to go across a couple of fields towards a road we can see. We thankfully sit on the side of the road, where she finds a bag of sticky toffees left over from about three walk's previously. We sit in silence peeling the paper off them about 2mm at a time until a car passes. She flags it down and asks them for directions. You can tell by the look of shock on the driver's face how far out we have come.
She decides to assume df will find his own way home and we follow the roads home. There's no pavements and the road is lined with prickly hawthorn bushes ether side so whenever a car comes we have to press ourselves into it.
Dm decides our spirits need lifting so starts telling stories about walks from her childhood. At this point no one else has really said anything for about 4 hours, we're all too exhausted and hungry.
We arrive home at about 10pm to find it all quiet. Dm has forgotten her keys so we're stuck outside. At this point we'll sleep in the garage if we weren't so hungry. At about 10:30 dm starts to worry and is thinking of phoning the police. We start eating the chives in the garden as nothing else is edible.
At 10:45 df appears at speed. He actually arrived home about 9:45 and found we weren't home so set straight out to look for us.
We get inside at last. Dm finds her keys were in her bag anyway. Df decides that we're all tired so should all help get dinner ready. I don't care about eating at this point and db has a temper tantrum and refuses to help. He will however appear when it's cooked and expect first servings. He then will throw another temper tantrum when told it's washing up time. He does this regularly not just after a walk.
We have fish fingers because they're easy to cook and fairly quick.
Over dinner dm and df talk happily about what a wonderful family day we've had and that we must do the same again soon. They remind us that we wouldn't want to be part of these dreadful families that might go out for dinner, wasting money, or do something that we might meet anyone, and tell us how lucky we are. I envy the people who go to a theme park and have dinner out. They probably had a good day.
Family time is overrated.
