Happiness is standing in the ocean and letting the waves pound against your chest.
Happiness is a cow stretching its neck up as you give it scritchies.
Happiness is your best friend geeking out with you about the Silmarillion when you two are supposed to be working on your philosophy essays.
Happiness is waking up in the early morning to rain, thunder, and lightning, and snuggling back into your warm covers to fall asleep again.
