We have all experienced days when everything goes wrong．A day may begin well enough，but suddenly everything seems to get out of control．It seems as if a single unimportant event may cause a number of things to happen．Let us suppose that you are preparing a meal and keeping an eye on the baby at the same time．The telephone rings and this means your troubles are beginning．While you are on the phone，the baby pulls the table-cloth off the table，destroying your half-prepared meal．You hang up hurriedly and attend to your baby．Meanwhile，the meal gets burnt．As if this were not enough to bring you to tears，your husband arrives,unexpectedly bringing three guests to dinner．
