If I am eating a mix of vegetables, I have to separate them into groups and eat the ones I like the least first, and finish with the ones I like the best. It's kind of annoying because it looks like I really hate peas (as that is my favourite vegetable, asnd consequently, to be eaten last). Extra annoying if someone asks me why I don't like peas.
It's the same with sandwhiches. If the bread has a soft, boring crust, I have to eat it first, then the delicious middle part. However, if it has a crispy yummy crust, I save it for last.
EDIT: I also eat my boogers. Yes, I am very ashamed of this. Yes, I know it looks disgusting, that's why I try to make sure noone sees me doing it. I don't know why I do it, but I have tried to stop and I couldn't do it.
