First, I'll just say, I've always loved the way you construct your poems. Two lines with rhyming ends... it flows really well and seems like you're talking more than anything else.
The first half seems really sad because we all know how true it can be! There are some that will stab you in the back and leave and all that. So it is definitely a poem you can relate to.
The last part seems a bit more upbeat, remembering good memories and all. Definitely an interesting poem to say the least. :)
