Billy, you are late again.
I'm sorry I'm late. I overslept. Is the manager here today?
Yes he's in his office.
Oh, I hope he didn't notice me.
Don't take any chances. It'd be best if you told him and promised not to be late again. He's already mad at you for last 2 times. Any more and he might fire you.
You said it. It won't happen again. Do you really think he'd fire me?
I think he might. You'd better go to his office.
You are probably right. I'll go right now and apologize. I try hard not to be late but it is difficult with Beijing traffic.
Good luck!
