Ah, underminers — those frenemies who, either intentionally or subconsciously, try to bring you down with faux concern and back-handed compliments. Their motivations aren't always clear, but their nastiness definitely is, especially when you're left feeling bad about yourself after an encounter with one. An underminer is especially terrible when you've made a new or interesting beauty choice, since they'll try to drive a dagger into any little bit of self-consciousness you have and exploit it to make you hate your new look — no matter how cool it actually is or how happy it makes you. I've had my fair share of showdowns with these kinds of people, since I don't appreciate their passive-aggressive attitudes, but do you know any personally? And if so, how do you deal with them?
