Do you flirt? In essence, flirting is about paying someone attention. The purpose of that can be sexual but it can also be playful and witty -- as long as the other person thinks so!

Sadly, flirting's image has been tarnished by the "pick-up artist" self-help books of the mid 2000s.

So how do people flirt well in the age of apps?
