Sum1 try to flirt wit me.. and

One of my friends suddenly ask me about this, if someone try to flirt with you, how you react?

Well I pause a moment, actually it never happens to me. but I will answered that, I already have boyfriends, and to that boi, you just too late lar..

She laughing to me and said, don't be to honest. Why? And she replying that I just so naive. I cant figure out what is she try to say. I'm quite blur sometimes.

Well may be I am, but when I think about it, I was trusted so well and I don't want to feel guilty/regret coz of my action later..

So if sum1 ask u about it, what is ur answer?
