You know I love a good joke as much as the next person, in fact I love them even more than the next person if we're being honest, and I always am.
I didn't appreciate these jokes, you want to remind me of all the fleas I have, or how good I am at playing man's best friend please then you should always do so, we wouldn't be best mates if you didn't - but do not ever insult my children again. I don't care if you think you were joking, or teasing, or anything. I don't want to hear it.
Maybe you should just let Lily look over your mail before you send it out next time - or you know just let her write it entirely. I know you're not this thick, act like it next time, mate.
Thank you for the congratulations, we'll talk to you both soon.
