I tend to have a slightly sarcastic nature (you can blame my super cool parents) and would like someone who can take that on and challenge me. I am very close with my family and very grateful I hit the parent/family lotto.
I am looking for someone who is confident but doesn't feel the need to flail it about. Someone who can laugh at themselves and has a good sense of humor. A person who has worked their bum off to get where they are and where they are going.
Lastly, I realize this should go without saying, but I do not like dishonest people. I take pride in my honesty and ability to own something when I screw up.
