As a little girl, I remember my sisters and I tagging along occasionally in the summers as my Dad visited his classroom for various reasons we often paid no attention to. While he might be doing an inventory of equipment and compiling orders of beakers, burners, and other scientific tools, we would explore the old and often empty building, climb up and down what we thought were dramatic staircases, play school, draw on the chalkboards, etc. My memories are foggy but happy ones.
