I've never really considered whether I'm an adult or not, I'm 28 so legally I'm an adult but how does that mean I should behave?
The gist I get from what other mum's my age do day to day is clean the house, cook, iron you know all that boring stuff, then they'll have some wine in the evening and watch soaps. They have dinner parties or go out at the weekend with their husbands or they have get together's with friends in which they drink, talk about men, soaps,gossip, make-up or whatever.
Wheras I do pretty much nothing all day (or I'll be web designing or writing), I clean when it gets a bit gross or we're expecting someone to come visiting. My husband does most of the chores like washing, cooking etc (he sucks at cleaning so I do that). I don't drink, I don't watch soaps, I play video games and watch movies and do random things like play board games or draw or write. To other mums that seems kind of childish but to me it doesn't, I just have different interests, some of which are more typical for younger people (like playing video games).
My husband and I also sometimes buy toys from our past, like he has a whole collection of TMNT and ghostbusters but we craftily get our daughter to like them too so nobody thinks we are weird
She didn't like the furbies I got for her though, I also like japanese characters like hello kitty and my melody, luckily she does too. So we have lots of little kitty things like our house phone is a massive hello kitty that lights up. On top of our printer/scanner is a huge doll that look like some 1980's hoodlum, we have gomez and morticia teddies sitting on top of a pile of books. We have boxes and boxes filled with toys, statues, dolls, figures, teddies and all manner of things. We went through a phase of buying toy guns to shoot at each other but then we got bows and arrows, we all got hurt and it all got a bit much. Oh and the inflatables I bought for my daughter's party 53 inflatables in such shapes as lollipops, baseball bats, minnie mouse etc we had great fun chasing each other around the house whacking each other with them before party day.
Oh and has anyone else noticed how awesome today's toys are? when I was little I'd have killed for some of the toys of today!
