C
I suppose when you grow up in one place, you have friends whom you’ve known since childhood．But as a child who moved a lot, my oldest friendships are with my cousins．
On our return from Guam, my parents, sisters and I walked off the plane in Alexandria．All my cousins were there to meet us．
I was excited to see them again．The last time I’d seen Don, Sherri and  David was two years before．That summer we’d caught fireflies(萤火虫) and watched Don and his friends play a game．Some boys acted like a bull(公牛) with a rope(绳子)．His friend held the rope and Don rode on it．When Don fell off, he got up and tried again．
Just like riding that bull, Don put his heart into everything he did．As a young man he was told he got cancer(癌症)．But he fought it and never gave up．Like what he did that summer, he held tight(紧紧地) , falling off a few times and trying again．I was excited and proud of my cousin for planning and going after his dream．I wished his ride would have lasted longer．
