To be not amused by this laughter?

[alaughingmatter]

It's incessant, disgusting, and grates. Every time I'm in the garden, all I can hear is this laugh. I wish I could describe it; well I could try. It's definitely male, begins with a loud intake of breath (resembling a honk - think low volume fog horn) then ascends to an unbearable countertenor, in an arpeggio-like-manner.
Someone is in their garden continually chuckling away, every time I open the back door. (And I'm honestly not exaggerating, it really is constant)
Tonight, the window is open as it's so humid, and I can't sleep because of the abrading arpeggios.
I have nothing against laughter, I normally find it a joy to listen to, especially a light "tee hee hee", but this is driving me insane!
So, there's the background info. AIBU, by hating this laugh, and dreading the next episode?
(Obviously I have nothing against the owner of this laugh, and I'm glad they're finding something very amusing, albeit, all of the time)

Laugh back like Sybil Fawlty.

Mulberry - No, it's definitely not a cough. Coincidentally, we also have 'loud coughing man' in our neighbourhood, who I believe, suffers from lung disease. The coughing doesn't bother me.
Takingiteasy- I hadn't thought of that. Maybe he actually has a laughing disorder? Either that, or his flat mate is a rather good comedian!
Well, I had a lovely cuppa in the garden this morning at 6am. Sun out, birdsong, and no laughing. Bliss! He's probably still asleep. I think I'm just going to have to take advantage of the golden early hours to get some peace and quiet!

AIBU to have laughed through this post?

YABU OP....why don't you start a collection of laughs? Like the man in Amelie. He could be the prize specimen!

tropicalfish if the dog can hear you but can't see you it might be worth a try speaking to it reassuringly, it works with the terrier in our road who can't see through the gate!
You feel like a numpty, but it's worth it if you stop feeling harassed in your own garden.

At least he doesn't carry on laughing in his sleep then. That's a blessing.

Really?

God sometimes I despair of MN.

Do you live next door to Rustie Lee? Anyone else remember her 'chuckle' from TVAM?

And yes, I am showing my age...

I sympathise OP. The bloke upstairs has a voice like a ruddy foghorn and is constantly on the phone in the wee small hours telling people off you never know though he might be telling himself off and I'd like to tell him to fuckoff too

Do you live next door to ?

Find out who it is by looking out for your most wrinkled neighbour?

Saskia- I'd find him bearable (just), at least there is some variation in his laughter!

Have you checked the garden for escaped hyenas or minor birds?

That's the man I was thinking about!
