Phone bill

The phone bill was exceptionally high and the man of the house called a family meeting...

Dad: People, this is unacceptable. You have to limit the use of the phone. I do not use this phone; I use the one at the office.

Mum: Same here, I hardly use this home telephone as I use my work telephone.

Son: Me too, I never use the home phone. I always use my company mobile.

Maid: So Sir, what is the problem? We all use our work telephones.
