A friend. Someone you know. Or someone you'd want to know because they're good to know. They have cool hobbies, they inspire you, they're absolutely hillarious, determined, charming, they make you want to write about them so that others can have a chance to be in touch with them. Congrats! This is the place to be.
And, because we also want to know what you know, you can write your Psst! for this category.
