I am just being nice

So, I am so fascinated by my generation. Obviously, we are much more accepting of things than that of our parents generation. For instance, I work with a 56 year-old guy who I absolutely adore and he is obsessed with Santana, CCR, The Doors, etc. He brings me his CD's and before we open the store for business I always play these CD's for him. See, I happen to like his music, but they're not albums I would normally put on. I mean, I would love to listen to Death Cab For Cutie or Postal Service everyday, but I don't because I respect him and I know he really enjoys it when I put his music on. The thing is, why do I have to tolerate his music? Why can't he tolerate mine every now and then? It's not like I would put on any hardcore rap because to be honest I don't even like that stuff. But if I were to play something like Scissor Sisters, he'd flip. Now, this issue doesn't make me angry or anything because I actually enjoy listening to what he has, but it just is interesting to me that I am expected to deal with it and play whatever he wants. Yet, I expect him never to listen to my music. Maybe I am too nice...haha!
