To peruse something
Can mean to inspect briefly
Or to scrutinize.
Comments: This was inspired by a fellow student in my Topology class, Natalie Rooney. When I accidentally let slip the phrase “a mere perusal of my web page”, she informed me that the word “peruse” means “to examine in depth”, contrary to popular belief. Having a great respect for Natalie, and not wishing to begin a blood feud with her that could last for decades, I thanked her for the information. But later (when I was safely within the confines of my remote mountain fortress in Tibet) I checked, and discovered that the word had both meanings. Hence this haiku.
