L.B.
I always had all the children over help pick up as I expected my son to do so when he was at a friend's house.
As they aged I still had his friends help out in the house. If you stay at my house more than one night in a row you are no longer a guest, is what I tell them. So they help set the table, clear, do dishes, take out trash, once, they all did the yard and cleaned the patio. Yet, they all still keep coming back! This crop of teen boys will tell me they do more at my house sometimes than at home - and they seem to like helping out. Odd teens.
