I have a couple of nicknames:
Noisy--that came about b/c at figure skating competitions and hockey games I have a big mouth and a skater's dad called me noisy. It stuck
Q--one of my sisters, Paige, started calling me Q last year, she picks a letter and calls someone that, mine was b/c she said she was too lazy to say Suzie Q.
Then I have many many embarassing ones that only family members call me (Magoo, Purple Burple, Susu<--from my nephews). Hey, I'm not ashamed. I respond to all of them!
