I need some insight on these. A&Aing them isn't hard (do share if you come out with some witty thing) but I'd like to know what sort of answer they're seeking.

"So, how long have you been single?"

"So, how long was your longest relationship?"
After it I noticed I could have taken a look at the clock and said "30 minutes so far", it'd have been gold.

"How come a guy like you single?"

I don't get what kind of value they're seeking. I'm unsure whether those shit tests are supposed to figure out whether I'm a clingy dude or to assess whether I can be persuaded into a LTR.
