After spending a weekend away with my adult son, I was so impressed by his generous heart that I sent him this letter.
Dear son,
I want to thank you for teaching me a very valuable lesson in life by the great example you   31  . When we were eating at that cafe in Boston and a person who had  32  his hamburger didn’t have enough money to pay for it, without   33  , you went over and   34   the extra $2 into his hand.
When we were leaving, you   35   threw a five-cent coin onto the pavement and said something like, “Some kid will really enjoy   36   this.”
Last week, a young man   37   me in the line at a petrol station didn’t have   38   money to pay for his petrol. I asked the money collector, “How much   39   is he?” She told me he had meant to put $15 of petrol in his car   40   he had been looking at the wrong gauge (计量表) and had put in 15   41  , which came to a little over $20. That is an easy mistake as both gauges run fast.
Something made me think of you and   42   you did that night at the cafe in Boston. I handed the man $6. He was so   43   and said, “But why would you do this for me?” I just smiled as I thought of you.
Thank you, son, for teaching me that “it’s   44   to give than to receive”. Now when I see a five-cent coin on the   45   and want to pick it up, I think of you and leave it there, just in case some kid will get a kick out of finding it.
Love always, Mum.
