So today I was in my english class begging for a ruler. People kept asking me "why do you need a ruler?" like it was odd or something. And I'd tell them, "to measure my hat!" and they still didn't get it.
Anyway, I thought I might do better if I used my phone to look up common objects that are 5.5 inches, so I can compare my knitting with said object. Well, all I got was Yahoo! answer people asking "Is my penis large or small if it's 5 and 1/2 inches?" Like a ton of different guys asking.
That was disturbing. I kept imagining myself hovering in a bathroom asking guy's about their...endowment. But I would never put my (white) hat under such torture.
Luckily, I found a place to measure my hat in the library copy room, on one of those cutting board things. I also have it on good authority that from my palm to my pinky is about 5.5 inches. Also my index finger is about three. This is good information to have.
