Yesterday I went to buy a gift for Father because her birthday    
was coming. That I bought for him was a book about how to        
keep health. The subway train taking me home was crowded,      
and I was lucky to get a seat. I sat there quietly imagining Father’s  
smiling, satisfied and happy face when he received gift. The          
train stopped at a station and an old lady with two large suitcase     
got on. Seeing her so tired, I offered my seat to her, though I feel    
tired myself. The old lady thanked to me and I smiled back at her.      
Maybe that was another gift giving to Father. I also realized that        
the journey would be sweet if you made it better for others!        		1. _____
