I'm writing this article in China, far away from my home in the United States. You might wonder what I do to remember my mom on Mother's Day. Well, l certainly call her to say "Happy Mother's Day" and promise that I will visit home soon.

I still remember the first time I forget Mother's Day. When I finally figured it out, I asked, "Why does mom get a special holiday? Why isn't there a Children's Day for us?

My mom explained, in that way that only moms seem to be able in explain, "Because every day is Children's Day!"

I knew that I had messed up. I thought about all the time and love my mom had given me. I thought about the food she had made, the toys she had brought and the long hours she had spent with me. There might not be a perfect mom, but there is mom's love, which can fix anything. After that day, for 364 days, I was looking forward to the next Mother's Day.
