Go on MIA?

Didn't attend school today.
Class Advisor wants to meet me and my mother on wednesday.
I know what she is going to ask.
I don't know how to answer, and explain.
Was suppose to accompany Sherri to shop.
But, I have no mood to go out. Sorry, Sherri.

Phone is back, but it's worse.
Lag like hell. Back cover is much loose than before -.-
Curse the person who repair my phone! Argh.
