That's one of the shit tests I'm hearing a lot and failing a lot. Answers like "posting stuff on the internets", "playing call of duty", "I don't really have much free time", "I'm looking for the one right girl, you have no idea how much time it takes" were failures every time I tried them.

Chicks want some DHV story out of it, but I really cannot think of any. I have troubles with DHV stories in general, when I try they just don't flow naturally.

So I cannot think of anything real I could say, or anything I could make up that would sound well.

Anyway back to the shittest. Any ideas for some really good answers to it?

As far as I'm concerned dude, this is not a shit test. To me, one of two things is going on here. Either a) this is a girl who wants to get to know you a little better, or b) she doesn't know what to say and is reverting to a standardized conversational piece.

a) This is a good thing! Take it as an IOI. Being honest is the right move here.

b) You should know if this is the case as it would likely be preceded by an awkward pause, and her saying "so... what do you do in your free time?". This means she's putting the effort in to continue a "lost" conversation with you. Again, just answer honestly.

The problem with your answers, I believe, is that there's no personality to them. It's just a factual response to a question. Girls aren't about facts and logic, but rather about emotion and personality. So give an honest answer, but add in some flavour. I would probably say something like:

"Geez, I didn't know this was an interview! Well, I like working out, hanging out with my friends, surfing the internet... you know, the usual. What about you... no wait, let me guess: (guess something outrageous)"

Easy asnwer:

"I dont have free time", after that you could say something like "Im kinda busy right now." SORRY BAD ENGLISH

But delivery of the message is the most important thing.
