These Love Notes is a social movement formed around three simple words: "You are loved." Its words entail ambiguity (Who loves me?) but comfort all the same (It doesn't matter, because I am loved.).
The idea is very simple: write the sentence "You are loved" on a Post-It note and stick it anywhere--inside a book, on a part bench, on a rooftop. The point is not who receives the note; it is that someone does in fact receive it. It is about spreading random acts of joy and warmth in the world.
