Her expression says, "Pink makes me gwumpy!"
Can't really blame her, though. I mean, they really surrounded her in Pepto, didn't they? (And she's a redhead, too. According to "old school" fashion, redheads and pink don't mix.)
P.S. Don't worry, redheads. I think that's an outdated fashion "rule". Go ahead and wear all the pink you want! ;o)
