Earlier today I walking around town buying some things and getting some food. I was not feeling really good, for some reason I could not make much eye contact with anyone. It might be because I'm having a bad skin day. But I atleast was dressed well. Well I was walking towards a restaurant and I noticed a girl coming towards me, I didnt even try to make eye contact because I was feeling down. As we are about to pass she says "hello" with a big smile. She said it in a very friendly way, and it threw me off. I didnt know what to do, I just muddered a light "hello" that was barely audible. And thats it, I just kept walking. I'm not sure if she was even interested or was just being friendly. But I am even more down on how I handled the situation. Just in a bad spot now.
