Before entering kindergarten, I had learned the alphabet slightly wrong. I understood it to be NOQPRS, thinking that the Q was similiar to the O with a tail and the R was similiar to the P, with the same tail. When I learned the proper way, I thought they had some national meeting to permanently change it from OQPR to OPQR and thought it was so cool that it happened in my life time.
