To be slightly pee'd off with friends with DC the same as age mine that won't do any child related activities. I'm talking going to the park together or swimming, we always invite them to different things, they say no as one of them is always out getting haircut/nails done or something similar. So their DC hardly ever do kids activities and they make us feel like we are a bit looney for doing kids things with our kids
the reasoning is 'sure they won't remember so what's the point'
It's not that they are avoiding us as they are always free for dinner or going for a few drinks etc at the drop of a hat.
