Thanks for sharing another poem of love with us at ES. This is certainly your field; and you excel in it with flair, as always.
I would have only one nit to pick, and igibson already pointed it out.
A thought can certainly be a memory; albeit a brief one.
I can understand the brevity of the memory, though.
A love such as you've described can only be coped with in small doses.
A love that can somehow encompass everything out of nothing; out of a wisp of coincidence and whim of circumstance.
Both painful and ecstatic, something this large within heart and mind can be overwhelming,
so, it may be best to remember in short, controlled bursts.
I can relate fully.
well, i dunno, it's kind of hard for me to understand, because there is a few lines that contradict themselves. like the first one:
A thought is all I have of you
Now my memories are gone
A thought of love once so divine
Forever to live on
I would say a thought that lives on, is a memory... I'm not trying to be a dick, and i hope i don't come off of it. On the better end of the stick, you have a decent rhyming scheme, and no matter how any person may or may not like this piece, any girl would probably melt over it. Over all, a decent job.
