how many dead grandmas?

na.

one idiot calls into work saying their grandma died &

the next week that same idiot tells their professor

that they missed class because their grandmother

died & the very next week calls into work saying their

other grandma died & a day later tells their prof that their

other grandma died & the classmates & coworkers talk

amongst themselves saying that the same idiot held other

jobs before this one & frequented other classes before

this one overflowing with dead grandmother galore---

how many dead grandmas can one idiot have?
