Girl waves, you wave back / realize shes waving to person behind you
A Socially Awkward Penguin meme.
Socially Awkward Penguin is a photo of a penguin waddling sideways against a blue backdrop. It's the advice animal of social anxiety: captions describe the cringe of everyday interactions - saying "you too" to a waiter who said enjoy your meal, waving back at someone who was waving at somebody else. Its opposite, Socially Awesome Penguin, shows the rare times it goes right.
