If you've devoted any time to a study of live tells, your game can be transformed, but you often have the problem of seeing your friends giving off glaring, unconcious tells and wondering whether or not you should help them by pointing them out. Bottom line is - you're all there to take chips/cash from opponents (even mates) and should use any advantage to its greatest extent. Few days ago, saw my mate demonstrate 7 massive tells in 3 separate hands (3 on same hand), which should have made his opponent run a mile instead of calling. Did I tell him what they were? Guess.
