Grandpa Li lives near our school and is over 70 years old.He has no son and daughter.Today he wanted to invite several friends to dinner at home but no one could give him any help.My classmates and I knew it and decided to help him with his houswork.Grandpa Li was very moved and asked us to dinner.We refused his invitation and went home without dinner.For this reason I came home late.Please forfive me for what I have done.I am very glad to help others.I think you will be glad too.
