I liked Randy's idea, so I am stealing it....
10. I do not have cable television
9. I do not have the Internet
8. When you talk about cable television or the Internet, I will act like I know more about it than you do.
7. I own all 5 seasons of Monk and will talk about them incessantly.
6. I use the word "actually" way more than I should.
5. I will try to convince you to read some book you do not want to read.
4. I laugh uncomfortably when I'm nervous.
3. When trying to think of things to say, I will end up talking about work, and NO ONE is interested in my work.
2. If I am not talking about my work, I am always talking about my family, being raised Mormon, or places I used to live/work. I talk about these things to people who are in no way interested.
And the number 1 reason you might think I am annoying....
1. Despite all my claims to the contrary, I actually do always think I'm right.
