Is there something wrong...with my teacher?

My Social Studies teacher (Mr.Cooper) is around 60 years old,and I just met him a couple weeks ago (I'm a new student). Lately I've been noticing that he doesn't laugh at little jokes made my his students (I don't make the jokes,just so you know). And he...

rarely smiles,and rarely laughs. He seems angry all the time. Also,today at lunch I noticed something quite odd:Mr.Cooper had squished his milk carton (Like a child does!) and then took his fork and stabbed the plate. He kept rearranging the packet that held the napkin and straw,too. Then he stuck his thumb in his mouth. Wtf? What's up with him?

If you're honestly concerned, you should talk to your guidance counselor.

It's possible he does have some sort of disorder that is known to them, but if this behaviour is new, he might need help.

I...um...Well...Mental Instution?

^^Scratch that^^
Its a disorder.

yeah you should talk to your guidance counselor about it. you may want to talk to your friends about it too and see if they all notice the same behavior

I have a teacher that likes to rub our arms O_O

Maybe hes just been having a bad time lately
...or he could be a fruitcake

Just don't sit with him at lunch lol, he might make a terrible mess, im betting he eats with his fingers and a bib? =]
