Hitting on someone is perfectly acceptable within limits and given parameters. I don't much like the idea of married people doing that, people get hurt that way.
I'm a firm believer that a man and a woman can be close platonic friends, in fact I have several female friends that men find desirable and attractive and we are just friends. As long as everyone keeps the same perspective in the relationship, there is no harm no foul. If the situation begins to change for either party, this needs to be addressed ASAP to avoid a good thing going bad.
oh yeah, those 5 plus minute conversations can get ya in deep trouble. LOL
Yes married people doing it is a bit weird, but I AM married, and I confess when flirted with I can flirt back but it is all about who with. I have had the fed ex guy flirt with me at door, but the UPS guys that come to my house are out of where I work, SO haha, won't happen but has in the building. BUT, there are two married guys that I work with and we have a great flirting back and forth that is FUNNY and works for us, and when you know nothing will happen with it, I think is all good?
