The sixth grade
Elementary school can be a great time for a lot of people and for others it is a nightmare. Kids can be mean and bully each other and only the strongest survive usually. But for those kids who were on top of the food chain back in the sixth grade, they want those memories back.
Maybe this person’s life just has not been doing well ever since they left high school or elementary school. If that is the case they should take responsibility for their lives and try to make the most out of it. Do not go back to girlfriends you had in elementary school and rekindle a flame that has been dead for some time.
