Another day at My Department

Have I mentioned that someone from my high school has decided to study my subject and is now hanging around at My Department? I kissed that someone 12 years ago, it was awful and I didn't like him. I never wanted to see him again the moment I got out of school...and now - here he is.
*yuck*
Ex Supervisor kept standing around me during the break of today's lecture. Didn't talk to me but desperately listening to what I said to some student. We were just talking about music. I'm not going to tell anyone that I switched supervisors. Ex Supervisor knows this. If he wants to talk about it, he just has to tell me. I will explain everything why I hate im in detail. But I'm no longer playing those funny games.
