am i strange?

The little folks on the bus had me thinking for a while. I always had the understanding that I communicate with a very small, specific group of people. A bunch of well educated engineers (or engineers to be) in an age range of 18 to 60 - don't let the age range fool you they have a lot in common. Basically clones of a prototype. I tried to get a feeling for the 99.9% of the rest of the community that surrounds me by talking to everyday people whenever I could.
All of that in mind, I had not realized how moving to Canada had narrowed down the group of people I was in touch with. My close friends, which are by the way quite a big group, are electrical and computer engineering students who graduated from Sharif and are now graduate students somewhere in the world. A step further, my other friends, with a few exceptions, are Sharif graduates who are also graduate students mostly in North America. How is that for diversity?!
Of course among my friends are people who are not engineers, who are not students, who .... but very few. Is this ok? Will I end up a normal person? These were things I was thinking to myself as I was walking in the mall shopping for clothes and shoes. Every once in a while someone would catch my eye and I would start thinking how different our worlds are! Am I a stranger to the outside world? Am I too distant from the average person? Is it alright to be such a minority or should I start doing something about it? Although I do feel rather comfortable as is, is there something that I am missing out on?
