Dear Son,
I don't normally write to you in a letter, especially since for the most part we talk quite frequently together about most things. I thank you for the fact that you open up to me, at least some of the time, and love the fact that you feel comfortable enough with me to do so.
I know that you are somewhat interested in sports, although I'm sure a lot of that has to do with the fact that Mom and I spend so much of our free time watch games, talking about games, and having people over for Super Bowl parties as we did this weekend.
