Is it okay if I farted in a toddler's face?
Why would you do such a thing to a toddler?
It is quite fun doing it to other people.
It's awful to intentionally try and fart in someone's face. I'm sure that wouldn't smell very good to the toddler, and could even make them sick!
I just really want to do it
Don't do gross things to others if you don't want them done to you. Find another harmless activity to do to tease people so everyone can have laugh.
