Your bright younger sister whom so many fancy to
Be you was always getting in the way when your friends
Were about.  An “altogether inconvenient child
With an alarming memory” one of them said once.
She would help you sometimes when a trick was to be played,
A pompous visitor to be derided, something
Lost, or broken, to be covered for; but for the most
Part, she was up to all her own mischief.  From her touch
Nothing was safe.  But then, what she did was all for show,
Nothing was changed, ongoings of every day outgrew
Her goings-on.  But it is your doings that have made
The difference to me; I walk down the boulevard
With you unnoticed: her red hat makes everyone stare.
