Sarah has been flaring her nostrils all day and thinking about the sizes of her nose holes. She stuck a pen in her nose earlier on accident and liked it. So, Sarah waits until she gets home, then collects a bunch of different pens. She takes each one and slips it inside her nose. She checks to see how snug each one fits inside her nostrils. The best fitting ones are put aside. After trying them all she takes the pens that felt the best and again slips each one up her nose.
