Mushy Peas

When I have a bite to eat at school, like lunch, I sit and watch my British friends using some strange methods to eat their food. First of all, they always take stuff and mush it onto the back of their fork, especially peas. And pretty much 100% of the school does it, so I feel like some weirdo who just got warped into Britain from a planet that doesn't know anything about British eating habits.
Another thing is that they sometimes take everything on their plate and make a mixture of all sorts of stuff. Usually, I keep most of my food separated, so I find it quite disgusting to see my classmates putting their peas in the rice and the rice all over the bread with a delicious topping of onions. Yuck.
