It's remembering the little things about and in relation to others that makes them truly feel special.
Silence is not caring, but the loudest words are deeds.
One of my favorite expressions is "all good". I say it to people when ever I see them.
I like it because depending on how the person hears it, it is either a blessing or a question. If they feel their heart has burdens they need to unload I care to hear, if not it is a blessing for them for all things good!
A person's hate is easily transformed in to love by their performing an act of kindness upon their object of hatred and so the greatest crime is not caring, for then love is never possible.
