Haven't you heard? It's a little thing called love at first sight. The exact moment you meet The One, you'll know. Actually, if 'Sleepless in Seattle' has taught us anything, it's that you don't even have to meet the person to know you're MFEO (Made For Each Other).
It's perfectly normal to be attracted to someone from the first moment you lay eyes on them. And after that, you may even get lucky and fall in love with them, marry them, pop out some children, and grow old with them. Stranger things have happened.
But if you think it's a good idea to see a beautiful man or woman across the room, gaze deeply into his or her eyes, and schedule the wedding for later that week, you have been deceived. It's not a good idea. It's a very bad idea, actually. Don't do it.
