This was a great poem.. it kept me hooked till the end. The flow was good, as was the rhyming. I really loved the fourth line in each stanza. They were my favourite.. very well worded.
Sweet memories linger and promise to last
I look to the future and hold on to the past
Your love was enough but it moved way too fast
And I wasn't along for the ride
^^ my favourite stanza. So cleverly written and again, the fourth line is placed very well.

I like how you didnt make the last line rhyme.. so it stood out.
lines like:

Into something I no longer knew.
Until it was too late.

Were just awesome.. Both of them are the ending lines..and i was just blown away at how you structured it.. very well done.

5/5

Nice. Very interesting rhyme scheme, and a great story. Yeah, kinda sad but you cant help be happy...Weird? Yeah prolly. But its how I read it I guess. Great job. I really liked it. 5/5

Wow i like how you interprete the title souvenirs.I could never tot of that as memories. It was indeed a sad write i can feel the emotions cascading through as i read from the start til the end.As first i kindda feel that your rhyming scheme is a bit weird being aaa/b/c/d/e etc... but as i read along i kindda feel that though it's weird but somehow you managed to pull it off and became unique in it's own way...Well the poem was certainly a delightful to read.Keep it up.

Excellent Job
5/5 from me

Wow !! Great job !! I really like how you portrayed your feelings and the structure and the words are very good. It is indeed unique, so great job again and keep it up.
