Why boys don't do washing up and girls aren't keen on woodlice

This year i am living in a house with 3 guys, apparently i am crazy. There are only three of us here at the moment (Barry plans to move in on the 22nd) and things have gotten a little bit gross. The downside of living with boys it seems is that they never do the washing up, it doesnt even seem to cross their minds to do it, even when there are no cups .... they just make do, what a wonderful existence it must be, sitting in your jammies all day shooting bad guys on the PS3, dehydrating rather than washing up a cup. It doesnt really bother me because its pretty much like that at home, im the only one who seems to care if things grow mold. So things pretty much go like this, i wake up 5 hours before everyone else (its lovely and quiet until 1pm), go around closing all the windows (because its blooming cold outside but none of us wants to pay for the heating so we wear big jumpers instead, however someone keeps leaving all the windows open .....) and then go to get breakfast and have to search for a plate even though im sure i washed up everything i used last night, there are various things growing mold that dont belong to me that i poke at with a stick from time to time to check they aren't dangerous yet. Strange thing is though if you say to the guys 'ewww this is gross!!! go do your washing up will you' they go 'what? oh *shrug* okay sure' and get right onto it .... its like they dont care about doing it they just didnt think of it. I dont get that. Its like laundry and showers, i've used the washing machine a couple of times since i started living here but im pretty sure i'm the only one and i have suspicions im the only one who takes a shower longer than 50 seconds. So im thinking that when we said 'boys are smelly' when we were 5 we were actually right. However there are some upsides of living with guys, if you find one of those sneaky woodlice that somehow seem to keep getting into our house, even though the front door is locked, and you squeal 'ahhh! woodlice!!' someone normally laughs and puts it outside, unless their feeling mean and then they try and throw it in your jelly. They're also not too bad at opening jars ....
