It all came from IRC. I always used the nick TangoKid.
But in my first times, when I was at a channel, hardly spoke because my English was too poor to make an intelligent answer when it was needed.
And when I WANTED to answer to something, I typed very hard, but the answer always popped up out of the conversation, and sounded like an enigma.
Then some guy nicked BulletProof said I was like the Sphynx, just sitting there and sometimes dropping riddles in the channel.
