An Important Lesson that You Learned

The important lesson that I learned is to be caution and careful. Last yaer I went to Florida alone. On my way back, While I was tranfering domestic flights at the airport, I was hurried when the officer was checking my carry on at the checking gate. After they checked my bag, I forgot my Talking Dictionary in the tray,because I was so hurried to go back home. After I arrived home, I just remembered that I lost my Talking-Dictionary at the checking gate. So this event it made me realize that I should be careful when I have to transportation.
