Teacher's office is unsafe

My head is filled with the plan that l must see Pak Dani, an art teacher who handles farewell card. He didn't provide farewell card as many as the sumber of the 12 MIPA student. A few days ago, M Azhar said that his card was not amongs the piling of cards and book report l laid on my desk.

As soon as l met Pak Dani, l asked him the card. He gave me the card with no addressee. I put the card on the pile, l tell myself l will write the addressee after l teach. I put the card for Azhar at the lowest pile and l leave the office room.

I see 10 MIPA 5 and 6 who are sitting down in hall to join GO seminar. I talked to Pak Hendra from GO about my son's plan to join GO. I gave him IDR 1.000.000. He said that the receipt will be given later.
We discussed about the role of teacher to help student to use etiquette when sending text or when posting things on Fb. I argue that the biography is being made anytime one posts something in mass media. 
My head said that my discussions partner did not like me talking too much as he must prepare his business in the hall. So l said goodbye to him and tell my student to collect their task later.

I return to teacher's office to check Alfira who will take SKHUN,  farewell card, and semester 6 book report. I found out that farewell card with bo addressee was not there. Who took it? What for? Why?

Card becomes one of things that lost in teachers office. A week ago, another teacher reported that her mobile phone was lost. Two weeks before, two teachers also reported that their mobile phone were lost. Teacher's room is not safe. Many belongings lost.
