Because you will always talk,
when the subject comes up (as you know it will) about the one that got away,
just like all fishermen and lovers do
and you will always keep trying to land one greater
and you will always find yourself straining to see her in the melancholy eyes of timid store clerks and uncertain artists that stab indecisively with gazelle-like arms at canvasses larger than their diminutive egos.
And you will spend days and years or more likely, a lifetime just like all great fishermen and writers do in constantly expressing that feeling of loss while searching for words and metaphors to describe that never-ending need to sleep next to someone who will remind you of her but never will never quite be her because there is only one catch of a lifetime.
