Don't do what you don't want people do to you

Ditched. I pity my friend because if I've left, it'd be like I ditch her. Instead, I stayed.
But in the end, I'm left alone. Sad. Yes, I am.
But to think back, I can bear with going alone. It's not like I never went home alone. Going to this certain class uses the same route anyway. So why not.

Just be strong. It's okay, dear. It's okay.
