Come to think of it, the true test of the extent to which you care about someone is your ability to be happy for their happiness. For the other end of the spectrum is too easy, it is basic human instinct, empathy and compassion with the wronged or hurt. It is only natural to be sad for someone else’s sadness, to share their grief or mood, to sympathise. You find yourself rising to a better version of you because circumstances are dire and you come to the rescue of friends, acquaintances or foes.
Yet to really know if someone is of significance to you, do you find it in you to be happy simply because good things have happened to them? Does your heart soar because they received and shared good news, because they’ve accomplished something, won something, were touched by the Lord’s infinite blessings? Does your mood get better? Do you laugh from the heart? Is your smile and congratulations sincere? Are you genuinely happy for them and proud of them? Then you do care my friend, for we are far more self centred a species to normally give a damn about the happiness of the other, anything above neutral is not usually worthy of attention, nor does it usually elicit joy.
