Firing questions at the Firemen

My friends had organized a tour of the neighborhood fire station for their kid’s birthday party. The fire men explained the various operations of the fire engine, the tools & equipments they use incase of an emergency. I was amazed at how smart the kids were in asking questions.
The fireman took out a long heavy hammer and axe out of the fire truck. Here is a funny conversation between the fireman and one of the smart kids:

Fireman: We use these tools to pry open locked doors incase of an emergency.
Kid: If you break open the doors then do you close them after you put off the fire.
Fireman: No, we don’t do it. The house owners have to fix it themselves.
Kid: If you leave it open then skunks may enter our house.
Fireman: mm… yeah!
Kid: Oh! I know what you should do. If you are there to put off fire in our house when we are not in home, you should call us immediately. That way we can bring the keys to open the door. Then you don’t have to break our doors.
Fireman: Good idea…
