It is a very weird feeling to know almost every school building I attended was torn down, save for my high school, which was, believe it or not, one of the buildings I went to elementary school in, that was bought by a charter school organization.
There is a particular subset of Millenials who feel "lost to time" because they were born at the precise moment where their entire time in Elementary, Middle, and High School was spent in these temp classrooms while their younger siblings had a normal life in the new buildings.
