It was the middle of the class when suddenly the door opened. Two police officers, each with one police dog, came inside and spoke "We are just here to check your bags. The dogs won't do anything if you don't panic." Without any answered they let the dogs loose. The dogs sniffed around. They both stopped at your bag. They were desperate to see what was in the bag.

This caught the police's attention and the both of them came up to you "Is there anything in your bag there shouldn't be?"
