When was the last time you did something for someone? I am not talking about giving blood,or building a house,or loaning money,although those are often fine things. And I am certainly not talking about donating to this cause or that,which are sometimes fine things but often not.
Rather, I am talking about smiling hello at someone. Opening a door. Helping pick up something that has been dropped. If there is such a thing as karma I think these are the things that count. The little things,soon forgotten on a conscious level by the other person but which help their day go a little better.
