4 kinds of kissing

Our 4 year old proudly claims (in the car the other night) that she knows the 4 kids of kissing. Then proceeds to tell us them:
1. Hershey kisses
2. nose kisses
3. mouth kisses
and
4. tongue kisses

wait what?! my 4 year old said what?!

So Matt and I look at each other questionly. I ask her "where did you learn about those?" She says "Tanya told me" (should have known!) She then proceeds to show me what a tongue kiss looks like. APPARENTLY it's when Tanya is pretending to lick her face. Lovely. All I need is my sweet little girl telling people she knows how to tongue kiss!
