Irked

I am not one for noise. For years I have suffered noisy neighbours, sometimes they were just going about their business and sometimes it was 'Boom Boom Boom' type music. I have been grateful these last few years that those days were over, indeed it is usually very quiet here. Imagine therefore my surprise this morning when I open a letter from the council regarding a music noise complaint. Imagine my stunned expression (on the other hand maybe not) when I realised someone had complained about me! ME? Who, what why where??????? 'Music noise complaint?' Radio 3 tinkles in the background most days with occasional 'Gold Radio' playing music from the Neolithic days of my youth so how come a complaint? I admit to playing some music occasionally loudly - about once every three or four months and then only a couple of tracks. It gets too loud for me after that! However nobody knocked to complain. No knock on the door.
Now only two people can hear my music, one next door and the man downstairs. Yet none have mentioned anything. It must be the quiet chap downstairs, the one who works nights. So I wonder why not knock on the door? Why not say something? I was puzzled to begin with and now I find myself annoyed!
After suffering the years of noise in the past I am always conscious of the noise reaching other flats, especially when I had six straight months of hassle here some time ago. Yet in spite of my care he complains. I am irked, irked I tell you! I should add he is very quiet. For the first couple of months he was here I used to lie on the floor and listen - just to see if he was alive! There was no sound! Usually there is a radio/TV or something, but no, nothing! Does he just sit there staring into space? Is he a plant for some alien world seeking to make a home here? Could he be contacting Russia because he is a spy lying low?
I will of course be my usual 'loving' self. I will continue to take great care re noise, but I am still irked. ME, making too much noise!Ridiculous! I am now officially irked.
