High Phone Bill

The phone bill was exceptionally high. Man called a family meeting to discuss the matter. Dad: "This is unacceptable, I don't use the home phone, I use my work phone." Mom: "Me too, I use my company phone. I hardly use the home phone." Son: "I use my office mobile. I never use the home phone." All of them shocked turned to look at the maid who was patiently listening to them all this time. Maid: "What? So we all use our work phones, what is the big deal?"
