My envelope was opened all the way- and clearly had been opened by a person rather than being ripped by something. So much so, that I would be inclined to think it was delivered to the wrong address, that person opened it - quite possibly by mistake, and then gave it back to the P.O. Because if any one wanted to open it by stealth, they wouldnt have opened it the way they did. It wouldnt be the first time my post has been delivered elsewhere, nor the first time that it was opened by someone else ( except last time it was an invoice for a rather expensive software package, and the person who it was delivered to rang up the software company giving out, thinking it was a scam, before realising it wasnt even addressed to them- I only know cause the software company rang me to tell me- the original invoice was never passed on to me) and I have recieved other peoples post too- but I didnt open it! Mr. Postman told me they got it in the subpost office already opened from a bigger post office.
