One summer when I was in college, my friend Ted and I worked on a crew back in our hometown, re-paving streets. Residents often came out to watch, usually kids and seniors. On one particular street, we saw among the onlookers the janitor from our grade school, now long retired. We greeted him warmly. He remembered us, we remembered him. The smile on his face I will never forget. How nice is that, that he felt so good knowing that we liked him as much as he liked us?
