Thank yous and apologies

Well it's Thanksgiving.  But, I don't plan on talking just about what I'm thankful for.
Of course, it's not that I'm not thankful for a lot of things, because I did have a lot of things to be thankful for.  Being fortunate, being lucky, having a lot of opportunities, all of that.  But I was well aware of that every day.  I just... wasn't the kind of person to say it all the time.

I guess I felt thankful for things that a lot of people wouldn't see as requiring thanks.  And then it felt strange to say it.
But then, if there was something to thank someone for, wasn't that almost something to apologize for?  You were making someone do something unnecessary for your sake.  It's like, you could say, "Thanks for waiting for me," or "I'm sorry for making you wait."  Or you could say "Thanks for giving me a ride," or "I'm sorry for making you go out of your way to take me somewhere."
I mean I guess most people apologize when they do something rude.  But, surely it was rude to selfishly make someone do something for you.
I suppose that was how I looked at the things I did.  But when I did things for other people, I always wanted to make sure that they didn't feel as if they were inconveniencing me.  I mean, it was just my choice, you know.  Or, you're my friend and I care about you, or... stuff like that.  At least, that's what I would probably say, if I were to say something.
