The marathon or the sprint?

The pursuit of a relationship, I believe, can be divided into 2 broad categories:

(1) The Marathon &
(2) The Sprint

The Marathon
Steady and long. Often does not display alot of passion but you see these couples together, everywhere, most of the time. Their companionship to each other is the forte of their relationship. You often wonder when are they ever going to tie the knot. You see the familiarity they have towards each other by their constant addressing of "we think", "we like" or "we don't" etc, when asked an opinion. They often don't make plans without consulting the other. And when one show up without the one in any occasion, EVERYBODY ASK WHY.

The Sprint
Fast and furious. Alot of passion displayed and when asked how long they have known each other, it is often measured in weeks. And in that matter of weeks, they have driven each other's car, called one another "honey", left belongings in each other's homes. Also, their public display of affection is uncanny. But alas, as what a sprint is, they die off as quickly as they started. And unbeknown to their friends, they are in another NEW relationship even before their friends know the old is over.
