This Causes A Sad Feeling
Actually more funny than sad. From a local 9th grader:
Q: What is a cause/effect relationship?
A: I would say that a cause for a relationship begins with a felling for some one. Then they begin to hang out and get to know more each other. The effects could be a good effect or a bad effect. Good in the way that you get to know that person better than you did before, bad in the way that if he or she moves then it causes a sad feeling.
