Don't know if I call it flirting or more fun banter???
And as Gayle said you would have to hit me over the head with a "I'm flirting with you sign" before I would know someone was flirting with me!!
Garinda will be able to tell you how bad I am at spotting someone flirting with me!! (cos he has had to tell me on a couple of occasions when someone has been flirting!)
