Then, he spent hours and hours on it it looked almost new. I was so of him that I bought him the shiniest helmet and a riding outfit(全套装备). I could wait for him to open up his gift. In fact, I barely slept the night before. Upon awakening, I went to the kitchen to the coffee, tea, and morning goodies. In the living room was a beautiful keyboard with a: “ To my wonderful mother, all my love, your son.” I was so. It had been a long-standing joke in our family that I wanted a piano so that I could lessons. “ Learn to play the piano, and I’ll get you one ” was my husband’s. I stood there shocked, crying a river, asking myself how my son could this expensive gift. Of course, the awoke, and my son was excited with my reaction. Many kisses were, and I immediately wanted him to my gift. As he saw the helmet and outfit, the look on his face was not what I was expecting.

So I wanted you to know, that kind of love still and lives even in the ever-changing world of me, me, me! I thought you’d love to this story.
