Happiness is a warmth. It has varying intensities, but it is some type of warming sensation.
It's the color teal, a mix between blue and green, producing a calm yet bright color.
It tastes like chocolate, milk chocolate—dark chocolate is too bitter, milk chocolate is sweet and smooth when it swirls in your mouth or goes down your throat.
It feels like that one type of hug when the person hugging you just keeps holding you tighter and doesn't let go and you don't want to let go and you just feel safe and at peace for the first time in a while.
It's hearing a person's laugh, and you start laughing because they are laughing, and so you're both laughing and you won't stop laughing for some time.
It's just the little things that make you smile and get you through the day.
