| One day I pulled up to my apartment building and noticed there was a father and daughter _1_ some things from a moving truck. Normally I'm shy away from contact with _2_.That particular day, though, something was in me; I can't explain _3_, but I felt like I should just help these people, even _4_ something as seemingly unimportant as unloading a truck. So I _5_ and introduced myself, welcomed them to the town, and asked them to give me a(n) _6_ to put some proper shoes on. After I had flipflops (夹趾拖鞋)on, I went over and helped them move all of their _7_ into the apartment. After we finished, we talked some and I got to know my new _8_. It might seem unimportant, but it seems like people are less _9_ and friendly to their neighbors these days; I wanted to 10 that, at least in my small 11 block. So we did talk,and they're from Florida, just like me. At that 12 time in my life, I was going through a really difficult 13 with my girlfriend of 7 years. I didn't feel like helping anyone or doing anything 14 , but I figured why not?And I'm glad I did. Also, as 15 would have it, their daughter is my age(college student)and we each had a mutual(相互的) 16 in one another. This developed into a friendship, and in the coming months, probably more. The 17 was the act itself, though. I got to know my new neighbors and made some new friends in the 18 . And I felt really good about it. Since then, I've tried 19 my comfort zone to perform other unplanned acts of 20 . So far, so good.I'd encourage everyone else to do the same! | ||||
