you know, i walk around with headphones on all of the time and it doesn't mean "leave me alone" so much as it means "i like to listen to music when i'm transiting by myself.". the idea that my headphones may or may not act as a disincentive to approach me has truly never even crossed my mind. not everything i do is meant to be interpreted in the filter of whether it is or is not ok to hit on me. i mean, does it logically imply that if i'm not wearing headphones then i'm inviting a conversation? this is a stupid discussion all around....
