My dog has a hair lip and also is gunning for this person.
I know this for a fact, all day long I hear, "mark, mark, mark."
Come to think of it, maybe that's the postman's name.
Mark/Marek... I have just put your mate straight about me taking calls for you by mistake and errrr Just to let you know that although he doesnt really believe me, he is off away to 'check his numbers'.
I am sure he will be in touch with you shortly.
