On Monday, my classmates and I heard that our astronomy teacher’s mother had died. We were surprised that he was still teaching in school. My best friend was telling me that the teacher was trying to forget the pain of losing his mother and trying to be strong in the middle of teaching.

The teacher was such a warm-hearted person and we figured that we should give him a lot of love and good cheer. That night after school, my best friend and I thought about our teacher as well as his beloved mother and then we came up with an idea.

When we went back to school yesterday, we gave him cheer-up cards which we had taken time to decorate with flowers, hearts and peace signs. As we handed the cards to him, we could both see the light in his eyes. The smiles on his face showed how much he appreciated what we did for him. The whole atmosphere was very warm and loving, and it’s hard to express in words.

This morning, when we both went to see the teacher again, he was so happy, and gave us both a hug. This made us feel that we just might have made his day, and that he was going to be okay.

With that, I want to remind you to take the time to smile at the ones you love, be extra generous with hugs, kisses, things of that lovely nature! Life is so precious (宝贵的), so let us be happy and enjoy the gift of life.
