Please.. Poem by Prince ....

I just sat there
as I saw you leaving
But I sat saying nothing
just silently breathing
I didn't want you to go
I wanted you to stay
I can't figure out why
It ended up this way
I don't know what
caused me to act as I did
I guess it's just me
Selfish, like a kid
Please forgive me
Please come back
cause without you
all i do is lack
Please, you complete me
Swear, promise, you do
Can't you just understand,
that I love and need you?
