While I can understand why you want to visit my awesome family, I am pretty sure I never invited you into my house. And if I did, you most definitely did not RSVP. Due to your rudeness alone, I am going to have to ask you to vacate the premises immediately.
Now don't get me wrong, I am sure you're nothing like the Bat/Pig Flu or the Plague, but I am also sure that I never needed to hear the sound of my child gasping for air or barking like a seal. You haven't made a good first impression and I suggest you get out before you face the wrath of an angry mother.
Oh, and while you're at it, please tell your friends UTI and Strep to hightail it out of here too. Thanks in advance for your understanding.
Goodbye and good riddance,
TMB and her three sick children
