<human>: Hey guys,

I'm a college student who goes to school very far away from where I grew up and where my parents still live. Because of this, I'm home about four weeks out of the entire year. My dad works very hard, and one of the reasons he does is to pay for my college and help me with living expenses until I graduate.

Tonight after he got home, we were talking, and I was casually watching TV. I seemed more focused on the TV than our conversation and he took offense to this. When he said something, I kneejerk-reacted and without thinking, basically said that I wasn't interested in talking to him at the moment. He took great offense to this and went to bed immediately. When I went to apologize, he said he didn't want to talk or listen and that he just wanted to sleep. So here I am.

My question is, how can I not only apologize for this offhand remark, but also show him that I truly care about him and appreciate what he does for me? Right now, I know he thinks otherwise, and honestly I understand why. I'm just afraid anything nice I do for him now, he'll think I'm doing because I feel like I have to.

I love my father very much and I don't want this little incident to destroy or damage our relationship.

Summarize the given text in a few sentences.
<bot>: I just said something stupid to my dad without thinking, made him think I don't love or appreciate him; I want to make it up to him.
