After checking the IRS info on the letter you got I thought of this poem
The Spider and the Fly
“Will you walk into my parlour?” said the Spider to the Fly,
'Tis the prettiest little parlour that ever you did spy;
The way into my parlour is up a winding stair,
And I've a many curious things to show when you are there.”
“Oh no, no,” said the little Fly, “to ask me is in vain,
For who goes up your winding stair can never come down again.
”
“I'm sure you must be weary, dear, with soaring up so high;
Will you rest upon my little bed?” said the Spider to the Fly.
“There are pretty curtains drawn around; the sheets are fine and thin,
And if you like to rest awhile, I'll snugly tuck you in!”
“Oh no, no,” said the little Fly, “for I've often heard it said,
They never, never wake again, who sleep upon your bed
Get help in advance and quickly because there is a time limit on taking action.
