I find the opposite with my friends. A lot are yet to have children and just have no idea what it is like to have small children, ie - I can't go and hang out at funky coffee shops at ridiculous times with a one year old! It is very hard now that we have moved interstate and I only see my old friends when I am visiting Perth as I can't just invite them over like I used to because I am staying with my parents or ILs. Sometimes I just wish they would invite us over to one of their places rather than suggesting ridiculous venues! Oh well, one is preggers now so will soon realise.... I also sometimes get a little jealous when I see my friends or old colleagues get promoted to positions I know I would be in had I still been working and while I would not change my life at all, sometimes I wish it was me... especially when a completely incompetent (and childless) old colleague of mine recently got appointed an associate!
