I'm not sure why I buy long sleeved shirts anymore. I will wear a long-sleeved shirt for about 5 minutes before I can't stand it anymore and roll up the sleeves and push them out of my way. I don't mind the three-quarter sleeve shirts, it's just the long sleeves that bother me. I try and try to leave the sleeves down for as long as possible, but it's usually not very long before I give up.
I don't know what it is, but maybe I don't like having my lower arms and wrist covered. Maybe it makes me too hot. Maybe I am just weird. Yeah, that's it. I'm weird.
