I'm sorry i assumed because you've done it before you might do it again.
I won't assume anymore.
I'm sorry i wasn't doing everything exactly how you wanted it done.
I'll try to be better at doing the tings I don't want to your way.
I'm sorry you chose not to sleep when you had the chance. I won't say anything when you complain about being tired.
I'm sorry my timing wasn't what you wanted.
I'll try to time my actions around your schedule more efficiently.
I'm sorry you're up late and you have a busy day tomorrow.
I won't keep you up with any of my issues.

I'm sorry I can't talk to you about any of this.
I'll try to be more open about it all.
I'm sorry I feel like I need to get out as fast as I can.
I won't go anywhere or do anything crazy.
I'm sorry I feel like everything's crumbling down.
I'll try to put more support where its needed.
I'm sorry it seems like you don't care.
I won't say anything but maybe you should be sorry too.
