School's Out

I have developed a bad habit of trying to school my friends in poker games. It all started when one of my good friends complained that he was routinely getting spanked in cash games by a group of old uni friends.  I stepped up to the plate and decided to give him some tips on hand selection, and we now play occasional cash games for fun and to help him raise his game, with a view to him getting even on his old mates. As a micro stakes recreational player I don't claim to be a poker expert, but I think sharing the concepts of 'It's o.k to fold preflop sometimes' and 'You don't have to see every river' are fair enough, plus my friend needed some help with bet sizing to avoid comedy overbets. The trouble is I keep giving lessons to my other friends when we play in different games. Some of these lessons are necessary to help the game run smoothly such as bet sizing in proportion to the last bet or raise, and dealing protocol. However I sometimes go too far and have begun to chastise stupid plays:  I have become an annoying idiot and need to stop because if people want to minraise the river with airballs and bet 1/8th of the pot with third pair, it is not my place to tell them otherwise!
