So i mentioned to one of the doctors at work today that i have a twin. You know its funny when ever i say that to anyone they give me this wide eyed terrified look as if to say "there is another one of you out there somewhere". Some people even go as far as to look behind them and around the room in a paranoid fashion. Although it is true that i have a twin he is nothing but the opposite of me. Kevin lives in Calgary and is married to a beautiful woman named Guila and they have a beautiful little girl named Isabelle (I wanted to name her Penny but i guess i will have to wait for the next one). Anyways Kev likes to work with his hands and is very good at figuring out how things work. He tends to be a work-a-holic and is never not busy fixing something for someone. Me on the other hand have a difficult time operating the can opener. Kevin is quiet and has a reserved sense of humour and i have a tendancy to blurt out the first thing that comes to mind. I often wondered if Kevin had been a girl if we would have been more a like.
Matt has a twin too. His twins name is Megan and she lives in BC. They are more a like than Kev and me but each have their own personalities. Matt tends to be a more outspoken and abrasive version of the Frewin kids.
Anyways i guess I would like to take this opportunity to educate all of you singletons out there what the most annoying question you can ask a twin is and perhaps you can avoid making an ass of yourself next time you run into one of us.
My biggest pet peeve is when you mention that you have a twin brother and people always say "Are you identical?" i often answer the question with, no he has a penis!
