Little Manners!!
As all of us must have noticed the way they eat their food...as if they are cannibals....I think the creators should look into that so that they behave a little while eating, at least when the guests are there.
Then there's a really irritating problem of the visiting sims that they move about the house as if they own it.....just putting on the TV as soon as they come in or just dig into any leftover foods without the permission of the owners.....it should be like when the headmaster comes and he does not eat until he's asked to.....
Then they should not start scratching their armpits in the middle of the road...well the dirty sims can be of exception.....then the farting thing is really irritating sometimes.....they don't even bother about who's there and who's not.....
I mean the rude sims in sims 3 can do it.....I hope the sims in sims 3 have little manners in them.
