Well, well, well, sweet Jennifer. If everyone waited until they were sure that they were in love, no one would ask anybody out ever. That's the way it goes. But the point is, you have to go on what little info you have and take a chance. When it's right, you'll just keep on liking the person until you grow old together.
Love takes time, like is enough to ask someone out.
Y'see, I'm in love with a girl in Hong Kong. The problem is I'm on the other side of the world and the only means of communications is with letters and e-mail. Dear X, Alas, another victim of love in the information age. The good news is that a relationship built on open communication and understanding has a better chance of lasting than one built on looks alone. The bad news is that Hong Kong is still on the other side of the globe and a plane ticket to get there is not cheap.
