Dear Abby

Dear Abby and her sister Ann
Both chose the same career,
A case of sibling rivalry, 
Or so it would appear.

When competition cuts too close,
It’s natural for some friction;
They didn’t speak for several years,
A seeming contradiction.

Eventually, they drifted back
And plainly reconciled.
Though they were twins, each might have wished
To be the only child.

It’s curious when siblings
Opt to follow the same track,
And rarer still when both succeed;
It takes a certain knack.

Now both are gone, with their advice.
They had their share of fame;
But each of them believed, I’m sure,
She had the most acclaim.
