Since I have mod powers, I am able to put little comments in my thumbs-ups. And since the other members of the forum ("the reglars") can't read then, I sometimes say hurtful and mean spirited things. Just helps me get my aggressions out in a harmless way, sort of like what listening to Metallica or whatnot does for other people (such as people whose hair is long in the back).
(I didn't put a mean comment in Ethan's or lasbar's thumbs-up, though. That's because I ain't feeling no aggressions as of late.)
