Being helpful. It's my life ambition to always be in the right place at the right time when someone might need help. When someone's in trouble, and I have or know exactly what's necessary to avert a crisis (even a small one), I get warm inside.
I love being prepared for trouble, especially small troubles. I like seeing the relief on someone's face when a serious inconvenience has been avoided. It's one of the reasons my backpack is so heavy, lol.
I want to be the most helpful stranger.
