Things you DON'T want to see in Sims 3

[Vigdis72]

And I dont want my sims to have to go all the way up the stairs if I change my mind and want them to do something downstarirs first.
Or that they cant get up more than one at the time. If they "crash" in the bottom of the stairs, should they be abel to wait a second and walk after instead of looking stupid and lose their memory of what they was going to do.
