Teaching your friends how to play is a bad idea IMO. Occasionally I'll get asked a question and I give a very vague, quick, non-committal answer that doesn't really challenge their beliefs. Besides, when the play at the table is really bad, I can't necessarily tell them what they're doing is wrong. Calling raises with KTo is definitely not something I'd do, but when people are raising with JT, then it's probably a good thing and I'm not going to try to sit down and give them a math lesson for a half hour when their experience tells them their opponents are playing even crappier cards than they are.

Back to the OP, as someone else said, at this level it's about fun. If your friends have a good time, they'll come back, period. Yes, they have to win occasionally to do that. If they play against other marginal players, the math says they will sometimes. So just make their losing experience as fun as possible. Casinos learned this lesson a long long time ago.
