Perhaps because your mind isn't given enough time Durga? Sometimes when something is really getting to me, I have a hard time putting it far enough to the back of my mind to allow words in a real paper book to take over and allow me to forget for that short while.
In that case, what do is put on my mp3 and listen to music. LOUD. Or I might shout at Marc ( who will shout back telling me not to shout!

) then hug me, tell me he's sorry for shouting etc., Sometimes we just need to vent first is what I'm saying
If the music is loud enough, you literally cannot focus on anything else. Dont do it for more than one song or two though!!! that volume for any length of time will damage your hearing and that's something none of us want.
If it's my neighbours creating a loud noise and it's gettign to me, I switch on iTunes, put on the LOUD mega mix and play oasis LOUD. I guarantee I do not get past three songs before they've either quietened down or gone out!!

works EVERY time!!

especially the song 'Hindu times' Oh, they HATE 'New Order' & Blue Monday.

the beat is literally like someone hammering on the walls LOL.....
I give as good as I get some times

Weeeelll.....If you can't beat them, join them!!
