<human>: When I was a sophomore in High School (2003), I finally started to grow a pair and became a little bit of a bully, compared to the timid 'loser' I was all through elementary school. I really only focused the bullying on a few kids... and in hindsight, I feel bad about it. 

In my grade there was a kid who we'll call Greg. He was my prime tooling target. I borrowed a friends cell phone, and we looked up Greg's phone number in the phone book. I called his house, and it went to voicemail. In the deepest, manliest voice I could utter, I left the following message: 
*"I have AIDS. Greg might too"*
and hung up.

The following day, Greg was absent. I didn't think anything of it, until one of his friends came up to me all pissed off because his parents actually took him to a clinic to get tested for AIDS. Not only did his parents force him to get tested, but they seriously thought he was gay for a while after that.

Greg and I patched things up, and we graduated on good terms.

Can you condense the text into three sentences or less?
