Love is always knocking at your door, you just don't realize it.
If love were mathematics, I would have mastered the whole calculation and learned the formulas off-hand.
If you know what love is, you know what pain is, just like if you stand on the tracks, you learn what a train is.
There are harder things than finding the right one. Like nailing Jell-O to a tree, for instance... but hey we did it.
