I found the absence of the comma troubling. You used punctuation, but only at the end of your lines. Line 7 could use a coma between the words "mind," and "marking." Likewise line 10 needs a comma between the words "moment," and "a." Also line 12 "mind" and "stopping."

This is my first comment here and I don't want to upset poets, but I just had to point these things out.

This poem is beautiful too...
It does have a nice go to it...i love it...memories are bad and beautiful too...remembering the past moment is Beautiful but reminiscing the end if the moment how it all ended or seeing where we are and where we once were happy..does make one sad..
I love how you talk about memories

What they are...what they do..

But I specifically love the ending....
Memories are nothing but or mind not free...it thoughts caged in the past....

Beautifully written...well done
