A weird dude

Theres this really strange guy in my class and I just DON'T understand him. Heres what he does. No, no no, he's just like... PERFECTLY NORMAL. (note the sarcasm)

When he's next to a really good friend of his, he strokes their ear. (Gay?)
Morning comes to school: He takes out laptop and plays the music at the loudest volume (Gay?)
He does sexual movements in Dance class (Gay?)
He sings during random times (Gay?)
The first comment he gives to a picture of my other friend's mother "YOUR MOM HAS NICE LEGS" (Gay?)
In the school bus he turns up the volume of a song in his computer and annoys everyone (Gay?)
He loves to put his arm around people's shoulder (Gay?)
He was being sexual to a girl today (Gay?)
He's probably reading this (Gay?)
He's mad at me (Gay?)
He's gonna kill me anytime (Gay?)
He's gonna kill me by humping me to death (Gay? Yup.)

There. As I said he's normal boy, except the fact that he's gay. I bet he thinks everyone's mother has nice legs. Such a compliment.
