It's a proper crime that, isn't it?

So I did a bad thing unintentionally. I found a letter addressed to someone with the same name as me [well, with a different but similar-looking first initial] for the flat next door. Clever postie found a way to halve time on his route by shoving all mail through the main letter box in the foyer instead of going through the ball-ache of actually delivering the mail to the seperate mail boxes just inside the door. So I was doing my good Samaritain/nosey parker act by performing the service the government's employees should be doing, myself. And I came across this letter.
It was a handwritten address and I assumed it was some dozey secretary mishearing or misreading my name. Turns out, no, there is a girl next door with a very similar name, who is [shock horror!] in even more debt than me. So, obviously I did the right thing and Pritt-Sticked the envelope closed and put it in her box. And went about my day with an ever-so-small spring in my step, knowing I'm not the only one in this swanky part of town with, let's say, cash flow issues. Good times. And to Miss L, do pop over for a cuppa.
