Today, one of my favorite Internet Cats, Maya, is #collectingkindness. Toward this end, she is asking people (I love the imagery of this) for pictures, poems, essays, etc about what they consider kindness to be.
To me, kindness is giving without calculating a return, without regarding how the other compares to you relative to color, race, ability, socioeconomic status, sexual orientation, or religion. Just giving, whether that be a smile, a favor, a conversation, recognition, love. No strings attached.
