给爸爸送伞(Send an Umbrella to Father)
it rained heavily in the evening. but father was still at work. i didn't think he brought an umbrella when he went out this morning. so i decided to take an umbrella to him.
　　when i reached the gate of his factory, father was not there. i kept waiting for nearly two hours. at last, father came out and we went home together happily.
