Today, I was waiting for my sister to get back with her friends and there older brother from a concert. As I was waiting, she calls me and puts the phone call on loudspeaker. She told me that her friend's older brother (who I thought seemed very nice and cute) liked me and that she wanted me to talk to him when they got home. When I asked if he knew they were calling, she told me that he was listening the whole time and that he was not saying no. I was really excited, because I like this guy. Well, when my sister got home, she was laughing and giggling. She told me they were joking. I asked who had started it and she told me it was her and her friend. She had even said that her friend's brother was not objecting to the idea and even made fun of the idea a little bit. Though, she did say he was smiling the whole way and that he was going to make sure to embarass them when he was out in public with them for making the phone call. I was upset and I felt stupid for thinking he could like me. Is ok to feel a little disappointed?
