My little cousin is greatly interested on science. And he does some dangerous experiments sometime. Although his parents want to encourage him to be great scientist, at times they worry about his safety. Last week, when my cousin was doing an experiment, he hurts his thumb. My aunt felt sadly and wanted him to stop from doing that experiment. However, my cousin didn’t want to give up. She said, “Many scientists got hurt when they were doing experiments, so they didn’t give up.” My aunt had to let him finish the experiments and he finally succeeded in finish it.
