okay...when chibi usa moves in with usagi and the rest of the tsukino family, it seems (to me, anyways) that her and shingo really like teaming up together to annoy usagi. shingo almost always tries to defend chibi usa when usagi and her are arguing. (of course, half the time, he was brainwashed by that pink yam head...uh, no offense, of course.) but...hmm, i say, why is this??? because!!! usagi annoys both of them, so why can't they team up?! plus, she sort of deserves it. pick on someone you're own size, usagi!!! heh heh heh. sure, i like usagi, but she does get annoying sometimes. come on, admiti it!!! at least sometimes you think she's annoying, too.
i think that if either one of them wanted to rob a bank or steal a huge diamond or a priceless painting or something, they would definately team up. i mean...come on!!! they're an unbeatable pair. chibi usa is incredibly cute, and she can hypnotise people and change the luna-p into anything!!! and shingo has the brains. well, moreso than the yam head. (that pink must have soaked into her brain by now!!!)
