Something that can change someones life can be seeing something bad happen right in front of your eyes. An example is like seeing a bad car crash happen right in front of your eyes or seeing a love one die. A other example is me. My mom died when I was 3 or 4 and the only memory I have of her was seeing her in her casket. For some years people made fun of me for not having a mom and that took a huge leap on me because I would hear things about my mom but I would never see or remember her doing or saying those things to me. A other thing that can change in someones life is having a new family member around because it could make you think of certain things. And one last example could be experiencing a divorce. Divorces are very hard to deal with and they happen so suddenly which can make one person very sad and upset. Bad things happen all the time and a lot of people witness it and it traumatize them but thats life and there is nothing we can do about it.
