Dear Mr. & Mrs. Smith,
it has come to our attention
that excessive Lint has accumulated in your lint vent.
We would not normally mention it but...
as your neighbors we notice that
every time you turn on the dryer, it snows.
Our car is constantly covered with lint
and it won't wash away, even when we go through the car wash.
We must also mention that our cat stays covered with lint.
It was a white cat.   Now it's a dirty brown.
In addition, the lint from your dryer is ruining our TV reception.  
(you've probably experienced this yourself on your own TV.)
that's not snow, it's LINT.
Also when we Barbeque, the hamburgers end up tasting like Lint.
Well done, but fuzzy!
So we are begging you, imploring you,
to clean out your dryer vent and return us to our normal life
Our Life before Lint!
It's the neighborly thing to do.
In closing, 
thanks for letting us Vent!

Sincerely,
Joe & Mary Snodgrass
(we live to your right, in the house that used to be white.)
