Be Mindful

This is another poem based on people in my world (real world).
It's about a certain boy in my class who, should I explain so briefly, is a show-off. He tries not to make it painfully obvious, which is commendable, but it's the same.
It's difficult for me to explain, but basically, he tries too hard to look smart.
Perhaps you'd understand better if I wrote out everything odd he's done, but that'd take too long.
