"Miss Maltby said she came up with the idea to wear a dog lead, and said previous boyfriends had called her a "wierdo" when she suggested it.

Mr Graves said: "She's very animal like, she's kind of like a pet, as well as a partner."

He said: "You wouldn't expect your cat or dog to do the washing up or cleaning round the house." "
Uh, yeah.
