A very long time ago, or at least it was a long time ago in relation to the number of years I have been on this earth, I promised someone that I would love them forever.
He responded, in an almost sardonic manner, that forever is a long time.
Yes it is and yet somehow, forever doesn't always seem to last quite long enough. We are warned that nothing lasts forever and yet no one ever warned us that some things do.
My love for others for example, apparently does indeed last forever.
The problem with a love lasting forever, is that we don't and our circumstances don't, leaving us forever longing for that which didn't last long enough.
