This is a great piece.The rhyme scheme blends in so subtley with the emotion of what you are saying.I can also relate to this poem for personal reasons.I know we all have things we wish we could do over.My feeling on that is this:
Save your regrets not for the things you did, but for those you didn't.And if you live your life following your heart, in the end perhaps there will be no regrets at all.Anyway, great piece, technicaly, emotionally, and intellectually.

Now this is my sort of poem!!! its just got so much emotion beautifully expressed. i really love it.
