Washing Instructions

So, after months of college, my big bro still hasn't learned all the tricks of the trade, especially when it comes laundry. Don't get me wrong, he's knows how to do laundry. It's just that he doesn't know the little secrets. He came up to me with a huge white shirt. He wanted to shrink this shirt. I simply told him to read the washing instructions. He read them off, machine wash warm, with like colors, tumble dry low....so, I told him to not follow the instructions...duh, instead, machine wash hot, with like colors, tumble dry high....that should shrink his shirt. I am so wise...he should listen to me.
