how come the min you go in the bathroom the phone or door goes

been waiting all morn for a call the min i go to the bathroom there goes the phone. lol do these people have a spy camera somewhere.
its a bit like the odd sock syndrome it dosent matter how many pairs u put in the wash you just know there not all coming back.
theres prob 100s of these scenario's  post a few if you can think of any and put a smile on someones face when its one that happens to them
