I'm ending with

I'm writing this all down
from start to finish
I'll start with
"I'll miss you"
You'll read this later.
I'm writing more down
continuing with
"Will you miss me too?"
You'll probably never find this.
I've got more to say,
"You'll lose my number
I forgot to save yours"
You'll have stopped reading by now.
I'm almost done,
just a little more,
"I can't remember if I said
goodbye or not,
I guess it doesn't matter."
I'm done now
I've finished
I'm ending with
"i'll miss you."
