Heh, I used to work with my mother, she was the head manager, I was a shift manager. When she was concentrating on something, she did not always notice if her name was called. After having my brother and I work there however, she *always* responded to "mom". Sometimes other workers would be saying "mother's name"..."hey, mother's name"....no response. Then "Hey, mom!" and my mom would say "Yes, what do you need?" It was pretty funny that she would miss her own name, but not "mom".
