The universe never tell us if we did right or wrong, it's more important to try to help people than to know that you did. More important that someone else's life gets better than for you to feel good about yourself. You never know the effect you might have on someone,not really. Maybe one core thing you said haunts them forever.Maybe one moment of kindness gives them comfort or courage.Maybe you said the one thing they needed to hear,it does not matter if you ever know,you just have to try.
