What does the boy’s father do for a living?

M: Come in, please. Make yourself at home.
W: Thanks. You have a nice place.
M: I’m glad you like it.  But the furniture is not good. We should throw it.
W: Don’t do that. It’s very comfortable. You have children, don’t you?
M: Yes, we do. Three boys and a girl. They often make troubles.
W: I know what you mean. Our children sometimes damage furniture, too.
