Look, chin hair is nature’s way of keeping you humble. You can pluck, wax, thread, shave, or zap it away. There is no “right” way—only the way that doesn’t send you into a rage spiral. I personally recommend a mix: tweezers for the loners, threading for the colony, and shaving for emergencies.
And remember: if someone sees your chin hair and comments on it, just say it’s a loaner from your inner werewolf. Then laugh menacingly. You are in control. Go forth and be smooth, you magnificent beast.
