I was in Sportsgirl browsing nail polishes with a friend of mine once, when a staff member came over and asked us if we needed any help.
"No thanks, just looking" we chorused.
"They're great polishes, aren't they!" She chirped, gesturing to the bottles labelled "Snowstorm" and "Gunmetal". "Those two are my favourites! Let me know if you need anything guys!" and with that, she dissipated to the bag section.
My friend looked at me dubiously. "Her two favourite colours are black and white?"
It was like that moment in The Simpsons where Lisa asks if you can hear a tree falling in the forest if nobody's around, and Bart achieves enlightenment.
