As a TV character, Sheldon is funny as hell, but in real life he would be EXTREMELY annoying trying to deal with. I could not work, live with, or hang out with Sheldon for any length of time without wanting to throttle him. And I daresay most people would have that same problem.
It may not be a mental illness, but his behaviour is well beyond what I think most people would perceive as tolerable and would certainly not find his company pleasant for any extended period of time.
Took the words out of my mouth!
There's someone on this board who reminds me a lot of Sheldon. I mentioned him on the previous page. Someone else had actually pointed it out before I'd even seen the show, so I didn't know what they were talking about. then I saw the show and I knew which character he meant.
That sounds a little harsh, but yeah, I see it as you do...he may be OK in small doses but in real life, if he were your friend you'd have to take him aside and give him a good talking to.
Sort of like Kramer from Seinfeld
in that way.
