I just wanted to mention the noise between the two flats as I think the ceiling is obviously very thin but I have been woken up several times when you’re moving about.  Sorry to mention this and I know it is probably something you’re not aware of but I thought I had to say something.
This is an extract from a handwritten note stuck to my girlfriend’s fridge.  It’s from her neighbour who lives in the flat below.  When I read the letter two things occurred to me.  One (pernickety): my girlfriend’s neighbour’s hearing is far better than her use of punctuation.  And two (panicky): if she feels she has to complain about the noise my girlfriend and her flatmate inadvertently make “moving about” what on God’s Earth must she make of the hullabaloo I make when I’m moving my bowels?  Because she’s absolutely right in saying the ceiling is very thin.  Sometimes when I’m sitting on the toilet in my girlfriend’s flat, I can hear the neighbour switch the light on in the bathroom below.  Now this is the sound of a light being switched on.  An ordinary household light switch; we’re not talking powering up the generators at Eddystone Lighthouse here.  It is not what you would describe as a loud noise.  As far as noises go, it’s quite unassuming.  Probably a little louder than a mouse’s fart but not quite as loud as a stoat’s sneeze.  Certainly no one was ever deafened by the sound of a light being switched on.  It’s not the kind of noise that warrants you sticking your fingers in your ears.  But if the sound of a light being switched on downstairs is clearly audible to me upstairs, then it stands to reason that whatever noise I make must also be heard downstairs.  And believe me, when I use the toilet I make a lot more racket than a light switch.  Imagine a Tiger Moth biplane crash-landing into the world’s largest Whoopee cushion phut-phut-phut-phut-parrrrrp-parrp- parrrrrp-parrp.   So if my girlfriend’s neighbour is looking for someone to blame for the noise, then I hold my hands up.  It’s a fair cop.  I am public enemy number one (or should that be public enema number twos?)  If she had perhaps been more honest, the neighbour’s note may have read something more like this…  
I just wanted to mention the noise between the two flats as I think the ceiling is obviously very thin but I have been woken up several times by what I can only describe as something akin to a volcanic eruption.  But given we live in Peckham, not Krakatoa, there must surely be some other explanation?  You’re not trying to land a Tiger Moth biplane on the world’s largest Whoopee cushion up there, by any chance are you?  No, that’s just crazy, forgive me, I haven’t been getting much sleep of late BECAUSE OF THE EVIL CACOPHONY OF BEELZEBUB’S RAMPAGING ARMY RISING FROM THE BOWELS OF THE EARTH. Sorry to mention this and I know it is probably something you’re not aware of but I thought I had to say something.
