My lucky day
I will always remember the date February 28, 2014. This was the luckiest day of my life.
When I woke up that morning, the sky was very dark. I took the early bus as usual. As soon as I arrived at school, it started to rain very heavily. Many students were late and were all wet when they got to school.
But I wasn’t because I caught the early bus, I would have been late and wet as well!
Later that day, I realized that I had forgotten my wallet and couldn’t buy lunch. I couldn’t believe it. Then my friend Lisa said that she could share her lunch with me.
Finally, my older brother told me that night that he could take me to the concert that I‘d been dying to attend that weekend. I was so happy!
I think that was the best day I’d had in a long time.
What a lucky day!
