When I was a child, my mom always arranged a surprise for me on my birthday. She always stood up before me and pumped balls, the number was equal to my age. When I woke up, the first thing I saw were the balls. Several times I woke up earlier and heard my mom blow up the balls in the kitchen as they burst. But I did not get up, pretending to be asleep and wondering when I woke up, so as not to hurt my mom. It seems like such a little thing - balls, and I still remember those moments with a smile and every birthday I want to open my eyes and see them.
