Dear Esteemed Co-Inhabitant of The Planet Earth:

It is only natural that from time to time, and in particular during the high pollen season, you may become overwhelmed by the generation of excessive amounts of mucus secretions from your nasal passages and need to expel them accordingly. But the exact middle of the sidewalk, or the doorway, or the very narrow stairwell is probably not the best place to do so.

Thank you and have a nice day, you nasty sludgebuckets.
