We, as humans, really love getting compliments. Next to free stuff, there are few things we appreciate more. Compliments make us feel like we’re special or have done something smart, even if it’s as simple as choosing an item from the fast-fashion store that ends up earning praise from an acquaintance. “I like that shirt,” she says, platonically. “Thanks, I got it at the mall,” we say, not at all sarcastically.
