@lisawhidbee: The Setup: Someone across the street or down a hallway enthusiastically waves in your direction. The Mistake: You wave back enthusiastically, shouting, "Hey!" The Realization: They walk straight past you to hug their friend standing two feet behind you. You seamlessly transition your wave into checking an imaginary wristwatch or staring intensely at a tree. #whoops #mistake #misunderstood
