Although he is friendly and chatty, he has a very dry sense of humour and is oh so serious and VERY level headed. He is definitely not one of those people that will laugh at every little thing, he is selective in what he finds funny, but he isn’t strict or anything.

What is bothering me is that on several occasions now when I have said something to him, perfectly ordinary, he smiles in that way people do when they are trying not to laugh. Like a suppressed smile. And he doesn’t want me to see it, it is sort of to himself.

For example I told him I would give him my work at lunch and he did that dumb smile before saying that that was fine.
Then most recently in the hallway I asked him about an article for the magazine and he did that stupid smile again, so much so I was about to ask him just what the hell was so funny (I wasn’t supposed to see it as he tried to walk around me while doing it, but I was looking right at him), he then turned to face me and told me that he would have the article done by tomorrow in all seriousness.

- He is not of a nervous disposition, he is very calm and controlled.

- On all the occasions, up until I said something to him he was always serious, as in he cannot have been laughing at something else when I happened to talk to him. It was always because I had said something to him.

I never see him do this when other people in my class say things to him. It bothers me as I feel like I must be doing something without realising. Any insight into why he is doing this? If he was generally a jolly jokey person I wouldn’t have taken any notice, but he isn’t, I wasn’t trying to be funny.

And before you all get at me for being paranoid/narcissistic/stupid I HAVE had an extremely.. bad.. experience with an older someone, nice at first, but it turned sour.. in hindsight the signs were all there, and they were ALL little things, just like this (and in a link i posted at the bottom of this) and I just ignored them. I have been on edge about contact with older members of the opposite sex since, I cannot get past it. So please tell me I am crazy. It cannot be happening again. Sorry this was so long. It is becoming a bit of a neurosis.

EDIT:// I have been watching how he acts for a little while under the advice of flutherites and friends, one of the first questions i asked on here was this

ach i need to get out of my head :(
