At first I thought I didn't have to but I also noticed how they criticised others for being boring or snobbish just because they actually prefer discussions on another level (more intellectual, for example).
I still talk to them though. We have other things in common. I just don't bring out the "serious and more educated me" into play when we talk.
I regularly find this to be the case. Whilst my outer demeanor is a bit random, I have a huge intellectual streak, and often have to hide it, or face a ribbing from people who don't know what I'm saying, effectively.
There is always "That Person" that you know where you have to do something like that. I don't mind because it's good for the ego and morale boosting when you know something that someone else does not know what the hell your talking about.
When ever I go out with the Rat Packers I have to dumb it down a bit. None of them are into science or have ever worked in that field, so I have to talk about low brow stuff with them.
Don't get me wrong they are a great bunch of Surfers but not the brightest crayons in the jumbo box.
They tease me and call me the professor alot when what I say goes over their heads.
