In high school a teacher once suggested that I be a math major in college. I thought 'Me? You've got to be joking!' I mean in junior high I used to come home and cry because I was so afraid of my math homework. Seriously I was terrified of math.
I have relationships with people I'm working with based on our combined interest. It doesn't make the relationship any less sincere but it does give it a focus that may not last beyond the experience.
