So I commented on a picture of this HB9 and here's how it went.

Me: Looking sophisticated. Nice.
Me: Nice "Folex" btw, lol.
Her: It's not a folex or a rolex for that matter.. its a michael kors. and who are you anyways?

Me:I'm a rock star..
I used to play lead air guitar for the band 'Casanova'

Then I appeared that she replied as I got a notification from it, and then when I looked, she had deleted her comment b/c it wasnt there anymore. So Then I did the same, I commented, and deleted it right away so then she'd get a notification with no comment.

So, I was thinking of maybe messaging her and kinda calling her out on the fact that she deleted her comment. And smooth way to do that?

"Me:I'm a rock star.."

This may have been the problem, im guessing you were trying to convey DHV? Not the right way.

Id recomment on the picture saying something like "But in all seriousness, im (your name here)" or something saying who you really are.
She was asking who you are, not what you do or did.
