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.
