There are a couple of people in my life who just love to constantly give me constant, unsolicited advice. I find it really irritates me, but I don't know if I've just got a chip on my shoulder.
For example, person will ask if I've booked a holiday. I will say that I'm going to Cornwall, I go every year and love it, they will then start telling me how they don't know why I go there, I should go to Devon/Weymouth/Timbuktu (anywhere but my chosen place). How they don't like Cornwall and I could do x, y and z in their suggestion. When I say I'll think about it but really I just love Cornwall, they go a bit huffy as if I've insulted them.
Same if I go abroad. If I say I've booked Spain they'll tell me I should try Tunisia. Even though I might have chosen Spain because the flight is short and we like Spanish food, for example.
If I paint my sitting room, they'll tell me I should have painted it a different colour. If I say I've used a certain brand of paint they'll tell me another brand is better.
If I say we're going for a curry to our favourite restaurant, they'll tell us we should go for an Italian at their favourite place instead.
They do it about my parenting. If I said I was taking the dc to our local swimming pool, that's 5 minutes away, brand new, has great facilities and the dc live, they'd say we should try another pool, further away, that's not convenient and has no parking, but they'll insist it's really good there.
If my child plays rugby they'll say I should get them into tennis.
They say the same things over and over again and always have to have the last day. So if I say, child loves rugby and is doing really well and the times are convenient. They'll say "well I think Tennis is better, but there you go". They do it about every single little thing we do.
Anyway, I'm sure you get the picture.
Having nothing to do with these people isn't an option. Not getting into conversation isn't an option, because they ask loads and loads of questions.
