Nancy didn’t like other people, so she kept everyone at arm’s length.
When she was a baby, her arms were stubby, so she couldn’t keep people from tickling her toes or getting in her face and babbling baby-talk at her.
As she grew, her arms grew too, and she could keep people a bit further away.
But still not far enough.
So, she had a series of surgeries to lengthen her arms.
Eventually, her arms were freakishly long enough to scare people away.
She enjoyed the peace… until she tried to brush her teeth and stabbed herself in the head.
