I slightly have the opposite. DH would probably say similar about me. But he usually rolls out of bed, and puts stuff in the car.
I check the fridge and throw away food that will go off, empty the bins, put stuff down the toilet so it smells clean when we come back, find a small extra space in a suitcase for one of the dc who's suddenly realised they can't spend a week away from something, put the security light timer on, check the windows are locked, drop a note to the neighbour if I haven't managed to catch them before, switch the freezer onto holiday mode, check the chargers are off, fill up waterbottles (although actually the dc usually do that themselves now), make sure the back gate is locked, check the car oil/tyres (or ds does it) and the error codes (we have a permanent warning light up, but it isn't a problem as long as there's no new codes), wash up the last few things that didn't go in the dishwasher and finally check the doors are locked.
Last time I left the latter one to dh we went away with the back door wide open. Not just unlocked. Wide open.
However I can tell you about the time we were going away as a child. To understand this, you have to know my df is paranoid about anyone knowing we're going away.
This is how it went:
We needed to leave by 9am.
At about 8:30am df started filling the car with suitcases. He'd got half the stuff in, when the postman came up the drive to deliver a parcel. "Going away, mate?" he says.
"Oh no," df says. "We've just come back."
So to add verisimilitude df then spends the next 20 minutes unpacking the car (while the postman is still down the road) and taking the stuff inside.
Packing the car take 2. We've got most of the way through when he looks up and realises that one of the houses backing onto ours is having their garage roof done, and the workmen can look down into our garden and see we were packing the car.
Dm persuades him not to unpack again. We get in the car and wait.
Ten minutes later df has got into the sort of clothes you would expect a country gentleman to be wearing as he goes round his estate. No, their's is a small house in a large village. Goodness knows where he got them from. I'd certainly not seen that flat cap before.
He proceeds to go to the garage and get out a spade and fork, and proceeds to start digging the garden, whistling loudly.
He then pops a head into the car and tell us to go and he will meet us the other end of the village. So dm gets into the driving seat and we should loudly "goodbye". We're getting good at this verisimilitude thing.
We park the other end of the village and wait 30 minutes for him to walk to us. He has changed into "walking clothes", and walking boots.
He gets into the driving seat and we drive off.
As we approach the motorway (20 minute drive away), he suddenly claps a hand to his forehead. He's come out of the side door rather than the front, which we do only when going away as the front door is more secure and you can then put the chain and bolts on the side door. To add to that, he's forgotten to lock it. In fact, he's not certain that he didn't leave the keys in the door.
So we turn round, and stop in a different part of the village so he can run home, lock the door and come back. An hour later he returns (this time dressed for sport) telling us he did a bit more gardening to make sure they saw him.
It is now nearly midday and dm is wondering if we should just try again tomorrow. We finally get away.
