Have you ever thought about the person by your side?
Their fears, their thoughts, their past.
Have you ever thought of what made them happy in the past?
Have you tried to recreate their memories? Their first kiss, the first time they ran with the person they loved at a certain time?

I have, and everything I do is smile. I can only smile at the past.
I can only smile at my past, and theirs.

I know it's hurtful for most people thinking about their partner smiling and having a good time with their exes, but I actually enjoy it.

The only thought of them being happy makes me smile.
