I only protect my younger friends when I really need to, or when something makes them feel unconfortable. I have a 12 year old friend who's in eigth grade, and her sister is 13 years old in 9th. The 12 year old said she felt uncomfortable when a guy in gym was trying to show off his risque movements, so I attempted to tell him off, even though what he did wasn't bothering me. I pretended that it bothered me too, because I really didn't want my friend or the seventh graders to be offended by him. But he told me "if it bothers you, maybe you just shouldn't look. This kind of dancing defines me. The seventh graders like seeing it." so i let him be, and told my friend to ignore him.
i can otherwise trust my 2 younger friends; they're obviously very bright, but they're often immature (they sure love to argue unreasonably about anything that goes against their religion). Yet i usually treat them like 15 year olds. I don't like being harsh on them, for they've been discriminated by many envious people, due to their young ages.
