I just want to know.........

I don't think anyone who isn't Penny could answer that, to be honest! But as we've seen in the show, he'd be difficult to deal with. But she has to, so she's learned.

I think when あなた around a person who can be rather annoying for a long enough time あなた just get used to it. Even Sheldon.

I mean in school there we're plenty of annoying people who hung around me but it gets to the point where it doesn't bother あなた as much because your use to it. I think any of Sheldons フレンズ probably feel that way (except maybe Amy) lol.

My theory is that it is a ladies thing. See around the guys, Sheldon rarely budges on his beliefs and idiosyncrasies, but during the show, so far only 3 people have managed to break him out of it...

Bernadettee, Penny and Mrs.Cooper....

See the pattern there? :)

I think Sheldon can be a little unreasonable sometimes, but around women he tends to not be so restrictive and usually listens when they speak.
