Wrong Answers
1. lol, dunno, wtf is sqrt?, weird dude,
2. Any single statement without any explanation, like "friends", "party" (lol

), "gear", "progress", "skill", "environment", "colors" (beware of LSD-addicts!!) so forth so forth
3. Anything game related, again single statements without explanations
4. Generic, offensive, vulgar. As the thread states no "be my gf, be my friend im lonely and emo"
5. Cant watch youtube on firefox (this was fixed)
Right Answers:
1. around 9, anything with 1 or more decimals, "hang on" (dude is interested enough to actually take his/her time to find out!)
2. "come with me il show you the perfect spot" --> "here i had this epic moment", real life story --> something witty, smart well-explained. Could be nutty, on of the better i've come across is:
"So im playing this tower defence (Warcraft 3) and my brother steps in with a water gun and soaks me through, I just manage to type "fuck im gettin assaulted" to the others in game and I run after the little fucker. My friend also playing the TD takes it seriously as i dont return his phonecalls and calls the town watch (group of parents patrolling at night) who shows up and gives me the bark of my life about making other pple worry and saying shit like im gettin assaulted, obviously I dont really get why they're there, but damn I got the scare"
I was off my chair laughing, still visiting that guy once in a while^^
3. See where the questions are going, your challenging the wit of the player, trying to see how he/she thinks!
4. This could very well be game related, play a prank on someone you both know, have a laugh, go do something nostalgic thing, play mission 1 together^^
5. "So this actually happened to me"

, or err.. single statements will do "EPIC".
*note anyone should realise that they can twist and turn these questions into the fray of a conversation whenever and however you want it, it's just a pointer, there is no reason to judge players like some in this thread do on a single "hi", if you put some effort into it, one might end up finding a friend and that; is never a bad thing.
