My mother was very self absorbed and class conscious. She raised me to talk with a 'proper' English accent. I started school and was completely laughed at. But mother continued to drill it into me. Years later when I was home from university on break she scolded me she was so upset that I sounded 'common' and how humiliating it was for her. For years until she passed I instinctively spoke around her in a pinched snobbish tone.

I notice when I am hypomanic that this to a degree returns.
