My Mom calls me "Heather Feather". That goes back to when I was a child. :) It's just a nonsense rhyming nickname.
I got teased a lot in grade school. Kids thought it was funny to chant "Heather Feather What's the Weather?" Lame.
My Sister calls me "Ho" (among other not so nice nicknames that I refuse to write here). It's weird and totally indicative of our relationship. We have our own twisted sense of humor that really no one else gets.
