Re: General manners
ummm when all three of ur around (the hubz u and the nephew) talk about something the nephew does but blame it on the hubby... for example if u dont like the dishes laying around... jokingly but on the serious side, tell everyone how the dishes need to go in the sink (or wherever they need to go).
Dont point the finger the wrongdoer... just include everyone in the conversation and hopefully the message will get across.
Strike up a conversation about something he's interested in... whilst ur talking, ask him to help u out with the stuff ur doing.. and things will get done
