DECISION MAKING MISTAKES

There is a boy in one of my classes who does drugs. The reason I know this is because I was on the pathway and and I saw him with a different person. They were just standing there talking , and they kept holding something to their mouths. Although when I went past them they quite talking immediatly, and stood there looking as if they had something to hide. I also smelled this sickly sweet smell that I know for a fact to have been pot. I have also seen random groups of people hanging around the pathway and other places, sitting around and smoking or other things. At first I get angry at them, because they knew what it would do to them when they started, and they still know. Then I feel pity for them, because now it will be really hard for them to quit. I actually don't know what to think. And that is a huge mistake that I know that people are doing.
