If someone you do not know come and talk to you, what will your reply be?
If that someone tells you that he knows you are the one for him, what will your reply be?
If that someone tells you that he is sure that he wants you to be his, what will your reply be?
If that someone tells you that he has a dream, and that is to spend the rest of his life with you, what will your reply be?
If that someone sounds very sure of himself, will you give him a chance afterall?
But... in actual fact, you got to remember that you do not know him at all...
