Love is like alka-seltzer. You take two capsules (you take two people) you drop them into water (you put them together) they float, they sink, they fizz, they eventually dissovle into the other (ditto for the people) and in the end you have what you started with- a glass of water, but now with residue along the sides.

Love is that residue. Even after you finish the glass, it's still there until you wash it off.

Even if you love and then leave, the person you loved is still there- forever- until you finally wash them off.

And save the glass to start it all over again, the next time you have an upset stomach.
