Demo:
My father was a self-taught mandolin player. He was one of the best string instrument players in our town. He could not read music, but if he heard a tune a few times, he could play it. When he was younger, he was a member of a small country
music band. They would play at local dances and on a few occasions would play for the local radio station. He often told us how he had
auditioned and earned a position in a band that featured Patsy Cline as their lead singer. He told the family that after he was hired he never went back. Dad was a very religious man. He stated that there was a lot of drinking and cursing the day
of his audition and he did not want to be around that type of environment.
我与父亲不相见已二年余了,我最不能忘记的是他的背影。那年冬天,祖母死了,父亲的差使也交卸了,正是祸不单行的日子,我从北京到徐州,打算跟着父亲奔丧回家。到徐州见着父亲,看见满院狼藉的东西,又想起祖母,不禁簌簌地流下眼泪。父亲说,“事已如此,不必难过,好在天无绝人之路!” 回家变卖典质,父亲还了亏空;又借钱办了丧事。这些日子,家中光景很是惨淡,一半为了丧事,一半为了父亲赋闲。丧事完毕,父亲要到南京谋事,我也要回北京念书,我们便同行。 到南京时,有朋友约去游逛,勾留了一日;第二日上午便须渡江到浦口,下午上车北去。父亲因为事忙,本已说定不送我,叫旅馆里一个熟识的茶房陪我同去。他再三嘱咐茶房,甚是仔细。但他终于不放心,怕茶房不妥帖;颇踌躇了一会。其实我那年已二十岁,北京已来往过两三次,是没有甚么要紧的了。他踌躇了一会,终于决定还是自己送我去。我两三回劝他不必去;他只说,“不要紧,他们去不好!”
