it's already night but you crave to drink a beer so you go to the 7E to buy some beer with your dog. you see a group of boy is smoking and drinking a beer. you see one of them is your schoolmate but you just avoid them then buy some beer.

when you come out from the store, you see a guy is playing with your dog. he is one of the group boy you saw before. he look at you with a smile on his lip

is it your dog?
