Julia's 40th birthday party

I went to an old friends 40th birthday at the weekend - the sister of my close friend who died over 10 years ago when we were both 40. It was nice to see some old faces and have a dance and - well - just get out! Was exhausted when I got in though. its so tiring having to get the kids ready as well as yourself and then keep an eye on them all night. Especially with Evie having a broken arm at the moment. But worth the effort. Should I really be this tired all of the time?
