Sorry I don't care....

My mom calls me, leaves a message, and tell me she has big news and to call her back cause it's important. I couldn't wait to hear what it was, so I called her back. I asked her what it was and she told me that she won the Led Zepplin lottery and has tickets to go see them and she wanted to know if I wanted to go. I told her I could care less and that I'm going to pass. She was a little bummed out that I didn't care about her luck.
