So this gave a good opportunity for a Vocabulary Day. It is always good to learn new words, especially if you are part Nubian where learning a new word can practically double your vocabulary. Don't worry, you Nubians out there, I am not going to ask you to do any math problems, but if someone in the future asks you what double means it means twice as much (2 banana peels instead of one).
Anyway: Askance.
adv. With an attitude or look of suspicion or disapproval. Suspiciously, doubtfully, dubiously, skeptically, disapprovingly, distrustfully, mistrustfully.
used in a sentence: "When Moldy appeared out of nowhere tippy-toeing along on her little dachshund legs in a royal blue jacket two sizes too small, Willen looked at her askance."
