高一短文改错
Yesterday I went to see my childhood friends Li Gang and invited to have lunch at his home.At the table,Li Gang complained what the dishes were not delicious,but talked to his parents impolitely.He also asked them for 500 yuan.It was such much money that his parents refused.Li Gang became very angrily.I felt very uncomfortable and found the excuse to leave.When I returned to home,I wrote him a letter.I tell him he should respect his parents and never behave like that.I hope she will follow my advice.
