where is my supervisor?

Like I said before, I don't know what to do at my office. I'm still new and my supervisor rarely give me jobs. for example is on Saturday, I don't know what to do and she gave me some legal document. she asked me to read it and comprehend it. But, it was all contained with some agreement about this yayasan. I've read it actually, but yeaahh,,, I can't fully understand it all. Some documents are just some SK so I don't have to read it right? :p

Today, at this Monday at 09.00 a.m. she hasn't come. I know that everyone here are wondering why Mrs. Dian hasn't com? or Wouldn't she come to work today?
Everyone in this room are back to their work, even Linda who is a new one like me, has back to her work. But I didn't know what should I do. So what should I do today? Should I do Mrs. Dian's work? I'm sort of understand some of her jobs but I don't know if I can do it all.
Should I text her first? hhhmmm,,,,,
Aaaarrggg,,,, what should I do? Where is Mrs. Dian? :(
