Sometimes when I'm alone and I find something funny, I either think or say out loud "L-O-L". And when I see something Not Bad, I think or say out loud "NB". and when I'm chatting to someone online and I go to the bathroom, I say B-R-B even though I'm alone and the person I'm talking to can't hear me. I never say these out loud around people, only when I'm alone. Is that weird...does anyone else do this?
