My mind went to VERY strange places with "turning on a small kitten", there.
We visit my in-laws (800 kms away) once or twice a year, and always have to stay with them, which means their 19 year old sleeping on the sofa, poor thing - they won't hear of us staying in a hotel. And then we have to do Family Activities.
Going away would be hard. They're lovely, but they have grown children, their idea of a holiday centres around big long elaborate meals (fine, lovely, but we have a toddler who is pretty wellbehaved in that she'll sit still and eat nicely for at least 20 minutes) and drinking.
They also tend to forget or ignore safety stuff; when we visited them and our daughter was a year old, they went out and bought a car seat for her, and were all excited about it. They also bought a stroller for her younger cousin (6 months) as we were bringing ours.
Get there, find out that car seat has been bought from second hand shop for $10 and is a long way short of safety standards. Find this out at airport, in dark, with no alternative.
On second day, go out with cousin, take both strollers. Find out that "specially bought" stroller has no straps. Spend a long time trying to persuade me that I should swap strollers with them so the younger child can have the safe one. Er, no. Mine can stand up and wriggle out of a stroller, yours can't, plus, I paid extra baggage fare to lug mine over. SIL wasn't asking, by the way, this was entirely MIL.
I'm pretty laid back, but my desire to have a holiday which does not involve fatal risks to my toddler and centres around something more than just eating out a lot clashes with their desire to sit around, get drunk and shout about politics for the least cost possible.
