It isn’t difficult to be kind. You don’t even have to like a person to be kind to them. Kindness is an action you choose to do. It matters not what the other person does or says to you.
Kindness has been called a state of being as in, “She was kind.” When in reality you have to do an act of kindness to be a kind person. It is a choice to do or not to do. A human isn’t just kind without action.
I challenge you to do one act of kindness for anyone, for no reason other than to be kind.
