Of aggrandizing advertising our mailbox feels flummoxed

We found our mailbox crammed
brimmed with discontent
Poor thing been stuffed & jammed
pouring out lament

Her plastic sides bulging
while overflowing
readily divulging
sad contents showing:

Though a lonesome magazine
found no private letter
Advertising byzantine
‘how to stay a debtor’

Gushingly touted
quite breathlessly!
All restraint flouted
quite fecklessly!

The box didn’t gorge itself
instead invaded
it’s just a lidded elf
pounced on, degraded
