Hansei — What is Really Important?

My neighbor down the street is Bob.  He has Alzheimer’s Disease and other ailments, and I feel bad for him.  For the last 2 months, I go to his house every Monday night to put him to bed.  Another neighbor and I pick him up and walk him to bed and tuck him in.  It’s been a very humbling experience — one of those experiences that reminds you that life is very short and that people and relationships are — above all else — the really important things in life.   But, why do I sometimes forget and get carried away in the unimportant?
