Just got back from my trip and was feeling incredibly exhausted so I did nothing but watch tv in bed for 3 hours and feeling a bit better. I went with an extremely high maintenance friend and I think that just wore me out. I have to be aware that I enjoy going to concerts more alone than with him.
During the U2 concert last night, a woman was rubbing her breast against my arm on and off for about 2 hours. I think she kept glancing at towards me. We were all crammed into the floor area but my friend said I was stupid for not trying to talk to her. I thought she just couldn't help because it was so crowded or maybe I'm clueless to flirting
