First, trust your senses. In particular, your sense of smell — follow your nose. Do you smell skunk in the air? Skunks give off a distinctive aroma, and there’s no mistaking it for any other. Skunk-sniffing is not what you’d call pleasant work. It’s not going to conjure memories of the beach in Aruba, or your mother’s kitchen, or church on Sundays, or your grandpa’s aftershave. No, it will only smell like skunk, and will only remind you of skunks you’ve smelt before.
