LOL!!
I have never gotten it either, and I am messy, let them crawl on me and gimme kisses. I also have a very strong immune system. Just keep in mind though, for the people that are freaking out, we all carry strep and staff in our mouths. A small cut in your mouth could let millions of bacteria in, which can travel in your blood stream and get stuck in your heart. That is known as Bacterial Endocarditis. It destroys your valves, causing them to leak, and then you die.
Immune systems people, immune systems!! Take your vitamins!!!!
