A postman appears to haver finally cleared up widespread confusion as to why letters sometimes arrive with the letter 'P' scrawled on the front.
Customers have been left baffled by the strange insignia, with often sinister conspiracy theories spreading like wildfire online.
Some even speculated the mark was the sign of dognappers casing which homes had expensive pets that could be stolen.

One person said: “It's what thieves use to mark your house to let others know you have expensive dogs.” But the real reason is far less worrisome, reports the Sun.
But a Royal Mail employee has now taken to Reddit to give an altogether more innocent, not to mention clever, explanation, reports BirminghamLive.
One Reddit user explained that the "P" allows the postman to do their job correctly and efficiently. And another reiterated: “It's the postie's way of reminding themselves that when they come to post your letter there's also a parcel for you.
"That's so they don't post your letter then find out halfway down the street they forgot to knock and give you your parcel. Or sometimes they'll write P10 or something on the previous letter - that lets them know they have a parcel for next door (number 10) but no letter."
It comes as Royal Mail said it will hike prices on all first and second class stamps. The move comes amid a barcode shake-up. A first class stamp will soon cost 95p.
The cost of a second class stamp will go up by 2p to 68p. A statement said: "Royal Mail has considered these pricing changes very carefully in light of the long term structural decline in letter usage and rising inflation.
"Letter volumes have declined by more than 60% since their peak in 2004/5, and around 20% since the start of the pandemic."
