I've never been good at "flirting". Or what I call flirting. I am a little too blunt and have always had the tendency to say what I mean.
I am very friendly, I smile a lot, laugh constantly as I talk, move my entire boy around as I talk, touch people, look them in the eye etc. This is not flirting for me, but people can perceive it that way since a lot of people attempt to flirt in that fashion. It is just natural for me. Sometimes I try to reign it in, but usually I just do my thing. I am married, and most of the time my husband is right there, so I feel that generally clarifies the issue of friendliness vs. flirtatiousness.
