flirt back if you are willing to accept that she might like you. if youre not, act professionally and just be polite. i dont flirt with people i know may have a "crush" on me. but if someones just a nice silly person, i dont mind engaging in some flirtatious fun, just as long as they realise my limits too. i will never do anything to jepoardize my relationship with Jenn, so i have strict limits!
