I asked this girl out, and she said yes but she was busy on the night in question. I said ok. I told her to let me know when she was free. A few days later i called her up again. I invited her to go out and get some coffee. She said she would really try to make it, she didn't. I spotted the brush off and decided to leave the whole thing alone. I'm not upset or anything, I just don't understand why she said she wanted to go out on a date instead of just saying no, which I would have been ok with. Can anyone explain to me why she did this?
