How I made my parents tear.

My primary school gave all the primary six students a “感恩杯” on the graduation day.In English,the cup is called a “appreciation cup”.My school gave us that cup hoping that we would serve tea to our parents during Chinese New Year to show respect to our parents who have brought us up.That was what I did to make my parents tear.On the first day of Chinese New Year,I served Chinese tea to my parents with the appreciation cup.After both my parents drank the tea, they started to tear.That was how I made my parents tear.
