how do you deal with someone who is 'over familiar' , acts as though they know you personally

@darkmere1983 Usually, strangers who act over familiar tend to not respect boundaries.

And sometimes you gotta be really strong with the boundaries you set,

@Fishy i see now, yes you're right there, it's all about keeping my cool, not losing my temper and being assertive where it's necessary.

@Fishy i'm the type who tends to bottle things up, then really lose my temper.
