One possible version:
Smiles are beautiful and important.A smile given to the right person at the right time can brighten that person's day.
I was once moved by a smile from my friend. Three years ago,when I made a speech on my first day of class,I was so nervous that I couldn't say a word.Tony, one of my classmates,sitting in the front row, smiled at me and spoke in a low voice,"Yes,you can."I was greatly encouraged by his smile.His smile was important because it gave me self-confidence.
I will never forget friend's smile because I've learned that something so simple can make a big difference.
