A childhood belief about classes

when i was in the 2nd grade my family moved, and thus i had to go to a new school. We had moved from CT to VA and things were quite different, everything seemed strange in fact. My first day at school i remember raising my hand to tell the teacher i had to use the rest room. she said," the lavatory is down the hall to the right." never having heard this word before i thought she was saying "labratory" and had misunderstood me. when i repeated myself and she again told me to go use the "lavatory" i thought...these people are freaks!! , no way am i peeing in the science room!! LOL and i wondered all day if maybe they did experiments on pee there or something. LOL
