You every wish you could read peoples faces more easily. I went shopping with my niece today for fish she ended up leaving me on the aisle with a female worker reason being the girl helping me was apparently giving off obvious signals while I just assumed she was being polite, later while queueing my niece gave me a glance when the girl handed me the fish i asked her what's up and said mentioned she left me alone to chat/flirt with the girl. The problem is this is not the first time this has happened quite often people bring it up after we leave the area. I don't know what's wrong with me as I can usually tell when others have a thing for eachother but I just don't see it when it comes to myself.
