Let's check the point total. Yes I was keeping score because I have no life. Meaningless flings 8, meaningful relationships 0. The flings win. However, as always, it is up to what each individual wants out of life.
Meaningless flings are easier, carry less emotional baggage but of course are less meaningful.
Which, come to think of it, could be a couple of more points for meaningless flings. Whether you are into meaningless flings or meaningful relationships remember one very important thing. If at all possible, when at your home, always, always let your partner use the 'guest' bathroom. You will be glad you did and don't forget the Lysol. Unless, of course, you like the smell of the elephant exhibit at the zoo.
