| A mother and daughter living in my community are two of the most unfriendly people I have ever come across in my life. They are totally 1 , mixing with nobody. As they drive past neighbors they keep their eyes looking away and make no sign of 2 . The only fame they have is making a nuisance (讨厌的人) of themselves to the local police station by 3 music played too loud, dogs barking more than once a day and any other petty (琐碎的) little 4 . On moving into this neighborhood, I was 5 of these two but decided I would make up my own mind. This proved quite a 6 to me as more than once either the mother or the daughter would knock on my door and blast (猛烈抨击) me with some 7 or other. I 8 answered politely and made sure I 9 as they went past my place and also made the effort now and then to make a kind 10 about their garden or pets. Time passed and in October, as part of the Kindness Rock Give, Maureen and I decided to place a kindness rock in their garden. Their 11 remained unchanged, however, and I continued to be as friendly as possible. During the Easter give, we decided once again to 12 these two unhappy ladies to our list and 13 a packet of cookies on their gate. Imagine my 14 when two days later they 15 at my gate and jokingly said they were 16 hanging their Christmas stocking on their gate, and they brought me a bunch of flowers! So, my fellow gifters, do not 17 on your random gifts of kindness. You may never know just what this 18 to others, nor how many broken or 19 hearted people you may just change 20 a simple act of kindness. | ||||
