I like pink too, but alas, no Phi Mu at Mason either... and I didn't come to love red until much after I joined Zeta (otherwise AOPi and A-Phi would have been contenders, had my decision been based on colors, lol).
Speaking of Mason, and in regard to fraternities, we have several members who joined us because they thought we were Phi Kappa Sigma during rush. I'm sure they have members with the opposite story.
I dropped one sorority because I was told they were snobby and extremely fixated on "looks"...and then two days later they came to lunch in these tiny black tanks tops that said "____: The Sorority" in pink letters. That sealed it for me. I feel slightly bad now, but on the other hand, we wouldn't exactly have been a good fit for each other anyway. They're nice girls, though. I dropped another group because I remembered them to be the girls giggling incessantly in the dorms in this pink jerseys at the beginning of school getting in the way and annoying the ever living hell out of me. Then their skit turned out to be able picking the right pair of shoes. That was the last nail in the coffin for me.
