It's the little things in life that count, probably more so than the big presents.
A few things come to mind - a surprise phone call from a long lost friend, watching a fox jump happily through the snow like a little kid (saw it from my office window the day after the snowstorm), a kind and helpful customer service person at a big organization (yep, happened a few days ago, lit up my morning), my husband setting a cup of tea or a glass of wine on my desk while I'm working, good news, a great find at a thrift store, a piece of chocolate, a small token of appreciation, twinkle lights.
Many of these are unexpected, many are not material, most cost nothing. What does that tell you? It's really easy to make people happy!!!!!!!! Say something nice. Show that you care. Bring something over. Find out how you can help. Be kind. That's all.
