I went to Pitt around the same time Alaska did. I was a class under her. Sharon didn't go to Pitt, but he worked at a thrift store (Avalon) on campus, and he and his friends were just known for crashing parties and being incredibly obnoxious. I didn't know him, he didn't hang out in my group (never that), but I knew of him. Nobody that I knew at the time really liked him, but I was a freshman and Sharon was in his 20s, so our paths wouldn't have crossed much anyway (I don't even think he was doing drag yet).
The summer after my freshman year my best friend and I decided to stay in the area and sublet an apartment together. We threw a big "house warming" party that many of the gays between Pitt and Carnegie Mellon showed up to. Eventually, Sharon and his friends show up. I didn't really want him there, but there were so many people there and I was buzzed by this point so I didn't think much of it. Anyway, halfway through the night I start to notice graffiti on my walls. Somebody's stupid signature all over my fucking apartment. I go into the kitchen, and see that whoever did this ALSO tagged the individual pieces of fruit in my motherfucking fruit bowl (yes, my roommate and I had a fruit bowl because we were - what? - CLASSY).
Anyway, at this point I'm drunk and pissed, and start screaming for the culprit. Somebody yells out that they saw the person go upstairs. I go upstairs, and in my bedroom (which had been roped off), was Sharon and his friends, SMOKING (!!!!!). I don't think they realized I was one of the people who lived there because when I asked who was tagging one of Sharon's friends laughed and pointed at Sharon, who then started cracking up.
I was drunk but I'll never forget it. I walked right up to Sharon, grabbed him by the back of his shirt, and literally dragged him out of my room, down the stairs, through the kitchen, and out the back door, where I was about to beat the tar out of him until my bff/roommate pulled me off of him. So I just cussed him out instead. He and his friends just yelled some shit back then left.
