G is for Grim
Grim: stern and unyielding, of a sinister or ghastly character, having a harsh or forbidding air.

There's only one person I'm terrified of (besides my mom) and that would be… Lin.
It's good that the grim Lin avoids conversation, because then it makes it very easy for me to never have to try and talk to him. He's incredibly scary and when he looks in my general direction, he looks like he's going to kill something. Hopefully not me.
I must be some type of fly to him, constantly annoying him with my buzzing. Or he doesn't even know I exist.
I hope it's the latter, because that sounds like the safer of the two options.
