Classic Poem

I WAIT on you all day, my home forsaking,
Thrice climb the Aventine tho' great the height is;
Now A can stop or draw a tooth that's aching,
And B perhaps may heal conjunctivitis,
To deal with scars is C's sole undertaking,
While D can cure a case of tonsilitis:
Had I a hernia to E you'd send me;
But I'm a total wreck—and who can mend me?
