Absence makes the heart grow fonder

This may be true, but it can also make the eyes and fingers wander!!!

Like everything else, if you deny somebody of something desirable, it's only going to make him/her want it more. Now, if that something is the hunk/babe that is you, then obviously being away from you is going to pique your partner's interest.

However, this only works up to a point. What happens if you "forget" to go back? Well, the heart isn't going to keep on growing fonder indefinitely. There will come a time when your unfortunate partner realises that you've done a runner. At this point (after much wailing and gnashing of teeth, obviously), your spurned partner will start getting rather less and less fond of you. Eventually, this will settle down to outright hate, but not to worry - you'll be long gone!

Note that it is only advisable to behave as abominably as this in certain isolated scenarios, like on holiday or on business trips. You wouldn't want to get a bad name in area where you live, now would you?
