We are visiting FIL for a short break - he lives abroad but stays with us when he visits UK 3 or 4 times a year. For the last 4 days of our 6 day stay we have gone with the flow letting FIL decide what we do for the day even though it hasn't always been very child friendly (smartish restaurants / long car drives etc). Today FIL has asked what we want to do but in a very loaded way suggesting we go sight seeing together in local town. My boys haven't been sleeping very well (probably as they are not getting a lot of exercise) so I suggested we go to the beach instead. I've been met with a very passive aggressive - 'well you can do what you want, doesnt bother me - go without me if you want'. I'm pissed off and feel that he's being silly and inflexible - DH thinks we should do what FIL wants as he loves doing the guided tour thing and we are going tomorrow. Am I unreasonable to stick to my guns. FIL is currently sulking in the kitchen :(
