I'm used to the "do you have a gf" question, and how to react in a CF way, but last week-end I got asked a variant I was not expecting, and got stuck a bit:

HB: "So, Mika, how is your gf?"

I answered immediately the good ol' "which one? ", but then was stuck and answered the question straight "well, don't have one right now"; hopefully she is young and has little game, so I was able to recover, but it still left me wondering how I could have made it better

with hindsight, I figured something along the lines of "I'm still in the selection process, there is a waiting list, you should try to apply "

What would be your technique against that?
