It's just that you are done with preschool or kindergarden. Soon you will get a [!] and it will notify you that you are starting another school.
P.S. Was it the preschool teacher? Or the turtle, flower, and or the arts teacher? If it is the turtle, flower, and or the arts teacher then you are done with school. You will get a [!] that will tell you that you have to get a job. Just make sure that if you want a job that deals with intelligance you have to have 80 skill points in that catergory. Or if you want to be a hairdresser then you must have 80 skill points in fashion. And if you want to be a nanny or the preschool teacher you have to have 80 skill points in the kindness catergory.
Hoped I've helped.
