     After suffering through many months of unemployment  (失业). my wife and I moved this week from

Colorado to Ohio. where she was starting a new job.Not knowing anybody there. we were pretty

concerned about how we'd get our entire home unloaded (卸下) without killing ourselves.

     We made a phone call to hire (临时雇用) a couple of college students to help with all the heavy

lifting once we got there.But one neighbor after another stopped by to help us.What?Have_we_moved_

to_some_other_country?Maybe_we've_died_and_gone_to_heaven!

     Unloading actually became fun and joy because there were so many wonderful new friends to help

when we worked.The more people helped. the easier the work became.We were afraid the job might

take days for the two of us alone. but it was finished in a few hours.Many total strangers would either

walk by the sidewalk or drive by to ask us if we were moving in.Many were happy that this old house

that had sat empty for so long was coming to life again.We were invited to an outdoor meal yesterday by

neighbors on the same street.

     All the time. my brain was resting on this new sense of hope that people can be so friendly to strangers.Among all the conversation were lots of offers to help each other in all kinds of ways.It's wonderful to live

in such a kind little town.I feel so grateful to be here. and wish the rest of the world could see how an

entire community can model  (做榜样) what it's like to help each other.
