My DH thinks I'm odd but my friend feels exactly the same way as me - so who is being unreasonable?
SIL takes her children swimming quite often - which is why DH thinks I'm odd.
But ...
I hate swimming baths in the UK. I hate being so undressed in public, I hate getting my hair wet, I hate the way your socks get wet when you're nearly dressed, I hate being cold when you come out of the baths, I hate the memories of used plasters and lumpy talc on the floor of the school baths etc etc etc.
I love swimming abroad. I like jumping into a cold pool on a scorching day, I like the fact I have a tan and look a bit better near on undresssed, I like the way the sun dries me off in minutes etc etc etc
I'm a good swimmer. My parents took me to lessons when I was younger and I swam with school. My sibling swam for the county. My parents never actually took us into a pool in the UK (that I can remember) but made sure we could swim well from a young age and we were very lucky to enjoy yearly holidays abroad where we all splashed around in the pool and the sea together. I don't feel emotionally unstable because we never went swimming as a family in the UK 
Therefore am I denying my child anything by not taking them swimming in the UK? My DH can happily take DC when old enough and I will enrol DC for swimming lessons from an early age.
I am more than happy to stand on football pitches in the rain, watch endless ballet shows, colour in, paint, bake etc etc ... just please don't make me go swimming!
So who is being unreasonable here?
