I just have to say this... While I do initially think the finger licking thing is gross, I've spent the last 2 years trying to not be a hipocrite. Which means I consciously think about everything with the shoe on the other foot now, or I think about other related things that I may have done before slamming anyone else for it. I realized that everyone is a hipocrite (am I spelling that right?) so I'm trying to improve that about myself..
So anyway..
The entire germ thing is a huge one to point out because just think about all the places you put your mouth.. Think about all the things you touch and then touch your face, or mouth, or whatever.. In your day to day life. Wether you're being intimate with someone, eating dinner at a restaurant, or petting your dog that licks himself all the time and rolls around on the ground.. Let's not get into cats that walk in litter boxes..
We can't avoid germs. Yeah it sounds gross, and I'd give someone a funny look if they licked their finger to take a ring off and tried to hand it to me too, but then I'd think about everything else and realize hey! That's nothing compared to what I'm exposed to daily. If I wasn't, my immune system wouldn't be worth a dime.
