Cellphone part 1 of 3

Last week when I arrived in the office I put my cell on my table as usual. After some hours of work Boss passed behind me (potentially dangerous to have Boss behind you), saw my cell and without saying anything, took it and started to frenetically open and close the slide. I continued working, thinking that he was smart enough to stop before breaking the phone. After a while, he put the cell back on the table and went away, without saying anything. In the afternoon I received an sms, I tried to open my cell's slide but it didn't work anymore.
