Today, I shared the quiet room with a tall ex-basketball player (I know because of his alumni t-shirt). He took a phone call and left like one is supposed to. But when he came back, he took a call right in the quiet room, and I found that thin line between pointed looks and getting your ass kicked.
I tried giving him a look when he first started talking, loudly I might add, and realized he's a LOT bigger than me. It's a delicate balance. After he talked for a few more minutes, I tried again. A weak pointed look isn't really pointed anymore, though. It's just a look.
Thankfully, he got up and left again, and I didn't have to find out where that line was.
