It certainly is harassment, especially when it escalates to being threatened or worse if I don't stop what I'm doing and reinforce the wrongly assumed obligation to chit chat and tell them anything they want to know about me, even when I don't want to. Apparently, I'm not allowed to go about minding my own business or saying no without risking the wrath of someones fragile ego. I've been met with the negative impact of catcalls more time than I can count. It is not flattering, it is frightening.
