With all the school shootings lately, it is a wonder that something like that has not happened here or surrounding areas. With today's society, I think that we should assume something like that will happen.
Many people become depressed.
Some know how to deal with their problems, and others don't. When the depressed make the wrong decisions, their choices are merciless, such as the various number of school shootings. While walking the halls you will hear a number of horrible things. Some of them are just rumors. But you never know.
