Excuses!

I'll say my lil bro is ill and that i need to take care of him for that day.
what do you think of this?

Bad, unless there are no French babysitters...

you could start coughing alot and acting a bit sick at work the next little bit...Then call in sick that day saying its only gotten worse. I've sone that.

Try asking some co-workers if they want the shift?
