every show needs a villan and Little house would not have been the same without Nellie Olson. she was a product of her mother who spoiled her rotten. taught her to be the snob she was. Nellie was more than a brat, she was a flat out little Bi***,{ Alison Arngrim used this word to describe Nellie herself} Alison did a fine job portraying this nasty little girl. did you ever notice that when she got married and AWAY from her mother she was nicer? I wonder what happened to Nellie in real life { instead of the TV show} update i found a youtube with Alison Arngrim she does a stand up routine and came out in one segment dressed as Nellie pretty humorous.
