My mother through her fine example instilled (慢慢灌输)within me the desire to help others. She
taught me to notice those whom others ignore.
The railroad tracks (轨道) were within a mile of our house. Beggars frequently would knock at the
doors in our neighbourhood in summer asking for food. They were often turned away. Others simply
ignored the knocks.
My mum always went to the door smiling. She would invite them to stay and have something to eat.
She would have me open up the card table and carry a chair out onto the covered side porch (走廊).
There was a nice view into the flower gardens, and it was cool even on the hottest days.
She would bring a red and white tablecloth and set the table as carefully as she did for any company.
She would pour their coffee and pile their plates with food and dessert. Usually she sent a packed lunch
with them when they were ready to go, too.Sometimes she would take the newspapers to those who
asked about work.
She listened to those who wanted to talk.She never asked what would lead them to be in this difficult
situation. It did not matter. She saw only the need. Some thought she should not extend this courtesy (礼貌). She would say, "In the depression (萧条时期) when my father was searching around for any work to
feed us, thoughtful people fed him. I am just repaying their kindness. I cannot offer them money, but I can
see they do not leave hungry and discouraged." My mum was quite a lady.
