Straddling Halfway

My cousin met her best friend
in a halfway house
but spent the following years
no better than halfway

It was the 70's hungover into the 80's
when everything was drugs and sex
but now it was the 90's and the parties
had crow's feet and a smoker's cough and
two black teeth

After continually proving himself
useless, my cousin left her man.
To win my cousin back
he decided it would be a good idea
to make her jealous by
sleeping with her best friend

Her friend obliged because
since her AIDS diagnosis
nobody slept with her

All at once my cousin lost
a mediocre man
and a mediocre best friend

and started going to the
parent/teacher conferences
and teeball games
