I eat my son's snot
Really, why would you eat your son's snot?
I think snot looks and tastes great.
I don't want to be rude here but that's a pretty gross thing to do. It's bad enough to eat your own snot but you're eating someone else's. This is something you should stop as soon as possible and keep to yourself in the future.
It's fine to enjoy it. The whole point of life is to live and experience new things including food.
While that is a great outlook to have on life there are some things, like snot, that are both unsanitary and not food. You are risking getting sick because of this. Instead, you should try a new type of restaurant and order a food that you have never eaten before.
