I was the pitcher for the baseball game and I had a good throwing arm.
Sounds like you had fun. Did you have a good experience pitching?
I don't think about it much
That is why you are a pitcher, you can throw things well. But if you're really good at it, you should be more proud because it can make others mad that you're not acknowledging the skills that they wish they had.
I don't care. I do it just because I like playing baseball.
That's good you are quite humble about it, but I believe you should be happy sometimes that you are so good at it. Lots of people try very hard but can't live up to you, so how about coaching them instead of leaving them envious?
