@Mixalopoulos:
A (not THE) right answer (but not the only ha-ha), I couldn't figure it out, my mind is too much away from "easy" riddles.
My answer is Dao, he-he-he...
Back to my riddle:
Come on humans don't be afraid to get embarrassed a little, that's the (practical) way of learning through to the core.
@haydee:
Thank you for trying out, I won't provide the answer until minimum 3 humans(Mixalopoulos got it?) i.e. 2 more give their shyness up and give a try.
Remember I am nasty at them.
