Listen, be attentive, reflect, validate, support, engage, respect
Listen to what the person has to say. Do not be dismissive of their statements or behavior. Reflect what has happened before reacting to the situation. Validate the other person's point of view. Support them where necessary and appropriate. Engage them in conversation and actions to sooth and comfort them. Respect that their decisions were made from their perspective. Often appropriate light physical touch in conjunction with words of affirmation is highly effective in displaying compassion.
