I'm not trying to imply you're overly thirsty personally... just that the practise isn't acceptable enough to continue, even if you only do it once a year.

BUT if it's generally accepted by most women you speak to that random street hollers are, however unintentionally, a 'threatening' experience... where's the 'grey' situation where you think it would be ok? When is it ok to risk putting someone in fear for their safety so that you can chance your arm at chatting them up?

Is that for you to decide? Isn't it "better to be safe than sorry"?

Is there a reliable visual cue from the target that lets you know she's safely hollerable or is it a lottery as to whether you'll scare or flatter her?

Why not just.... stop doing it and holler in situations where everyone's comfortable and prepared?
