Well... my first attempt to enter a Secret Club wasn't successful (see: The Secret Club), but this time I'm sure that nothing can stop me from reaching my goal...
I've discovered this new club, whose members are some puzzle fanatics who love wasting time creating and solving riddles... what losers!
By the way I don't really care what they do in that club, but I want to be a part of it!
A fat guy is standing at the door, waiting for members to come.
And (you wouldn't believe it...) every time that someone approaches the door, this guy asks him in a very loud voice some strange question... let's listen what he's going to ask to those guys coming to the club...
First guy: "Hi buddy, can I come in?"
Fat guardian, screaming: "Tell me... what number immediately follows 7?"
"Mmm... 8, I guess!"
"Ok, come in!"
A second guy approaches, and the guy at the door screams again:
"13 - 12?"
"Too easy... 1!"
answers the second guy, and once listened to his words the guardian lets him in.
"What number comes before ten?", asks the guardian to a third guy walking to the club's door... "Well... 9, without any doubt!"
The fat guy nods, then asks again "1+2?"
"Hey buddy, who do you thing you are talking to?!? Everybody knows that the answer is 3!" answers the guy, and the guardian lets him in friendly patting his back.
(- Once again, it seems clear that entering a club is just a matter of elementary maths... Why is it always so?!? -)
One last guy approaches the club, the guardian smiles at him then yells:
"Hey buddy! Give me a five!"
"Hi Bob!" tells the guy, giving an high-five to the fat guardian and entering the club's doors.
(- Well, it seems this last guy is really well known... Anyway, it's my turn!... let's go! -)
"...ehm... Hey Bob! How's your day?... Can I come in?..."
The guardian doesn't seem very friendly... he looks at me askance then yells:
"Tell me... 2 and 2 make...?"
"I know the answer! I know it! It's 4! It's 4!!"
I scream... once again, just a second before the guardian kicks me away, telling me to never come back!
So I keep wondering...
WHAT WAS WRONG WITH MY ANSWER? WHAT WAS I SUPPOSED TO SAY?
AND WHY COULD SOMEONE ENTER THE CLUB WITHOUT ANSWERING ANY QUESTION?
You don't need any particular knowledge to answer the guardian's questions (except elementary maths, of course...).
Not everything in this puzzle is what it seems.
"HEY! IS THIS SUPPOSED TO BE A HINT?!?", I can hear you screaming... Yes, it IS!
Among things that arent what they seem: NUMBERS. Try not to consider them as (just) numbers. And be sure you have actually found all the clues hidden in my 2nd hint...
Try thinking out-of-the-box, and try changing something in the text of the puzzle according to my first 3 hints (in particular, n° 2 and 3). Isn't it strange the way the guardian speaks? Why does he keep SCREAMING?!?
