Check what I found in
the Wikipedia entry about Karen Brewer. You have to scroll down to the bottom, where it says;
"In certain instances, she deliberately disobeys her parents' rules (such as buying toy guns for herself and Andrew in BSLS #65 Karen's Toys) and she has a habit of stretching the truth. And being a horrible....horrible person. In spite of these faults, Karen is still portrayed as a loyal friend and a kind sibling."
Ha!
I never really cared for Karen, even when I was little.
