Me: (Talking about germs, coughing into your hands, not putting your hands in your mouth, nose, etc)
Student 1 (who is very shy usually): "Miss Stephanie, My dad picks his nose."
Me: "Oh. Well that probably isn't a good idea."
Student 1: "And then he puts it in his mouth."
Me: "Well. That really isn't probably a good idea. There are a lot of germs when you do that."
Student 2 (very earnestly): "Miss Stephanie! My grandpa farts....when I pull his finger."
Me: "Oh......Wow.......Actually, my dad used to do that too."
