i always make it a point to tell my youngest brother(who happens to be a copycat*meow*) this
"eh. wilbert ah. what jie jie doing is wrong. dont follow ah"
when i'm doing something deem as wrong in people's eyes.

guess its not working.

maybe i should change to
"WILBERT! what i'm doing is WRONG! if you copy, i will whack your ballsbeat you."
