Honestly I've no idea where the dustpan and brush sets go... are they eaten? Stolen? Misplaced? No idea but it's infuriating when I go to use it and it's not there!
They go "missing" because no one puts them away when finished using them.
Of course, they may have run away due to their severe dust allergies -
"Recent studies have suggested than many household brooms suffer from allergies to dust and dust mites. Both the the BSACI and the NIH have published studies claiming that nearly 94% of all brooms in the world suffer from some sort of dust allergy. Marion Newblester, a spokesperson for the NIH, says that people should check their brooms' bristles. "A good indication that a broom has allergies are frayed bristle heads. The more frayed the bristles, the more severe its allergies." Newblester also noted that some dustpans may also suffer from allergies, however studies conducted so far have been inconclusive."
