Two comments, here they are.
Time
About how people spend far too much time worrying about the past...
**********************************
This poem is something I'll try to remember,
I think I worry too much, I'll start to surrender
My choices of the past to the past and move on,
Look to the future, let bygones be bygones.
Forget
About the forgetting the guys who don't return the feelings...
**********************************
They'll always be there, somewhere deep inside,
In the back of your heart, the back of your mind,
I'll never forget them, no matter what people say,
The crush may be small, but the marks will still stay.
