Donating blood

Helping people is the way to be happy. At school there was a donating blood activity two days ago. I went to donate blood with my friends owing to I wanted to try it. While we were waiting, my friend told me that the needle head is bigger, and it is inserted to your body, you would feel a little painful. I was afraid of her words. But in fact, when the needle head was inserted to my hand, the nurse wanted me to breathe deep, a result, it was not painful. I did not know why I was happy after donating blood. Maybe in my mind I thought I had a good job. After this time, I love to donate blood.Donating blood not only promotes the circle of blood but also helps the people who want blood urgently. In the other hand, some day perhaps we also need others caring transportation. So, you all often donate blood!
