For R:

July 24
I've had enough.
No idea where you were, I said goodbye.
I was ready to leave you behind.

July 29
But you came back, and sent your apologies.
A bit guilty, I forgave you.
But this time, it wasn't going to be the same.
I said enough, you agreed.
It's just not working out.
Let's be friends. It's probably for the best.

Today
Keep writing.

( For J, the youngster: )
