     Things always seem different from in normal (平常的) times to people when he or she is not feeling well.

Perhaps, many of us know this rule, but we do not care about it. At such times, things make life hard for

people in little ways. For example, when I am not in good condition, I can never find the things I need. To my

surprise, it seems that the things I need have moved from all the places where I expect to find them. If I need

something, I can never find it quickly.

     Sometimes when we are not well, we will find that boxes become heavier when lifting them, that doors

don't want to open much more easily when trying opening them, that wind becomes even colder when facing

it, that the sun becomes much hotter when under it, that cars don't run better when driving it and the distances

are longer than they were when we felt fine.

     Why does it happen? The things around us usually do what they should do as long as we are well and strong.

But when we aren't in good condition, things often tell us that they are really not our friends but our enemies.

It is wrong. In fact, everything keeps the same. Only because we are disturbed (打扰) by the bad mood (情绪),

we get the wrong feeling that everything is in the opposite direction against us. If we keep calm in the bad times,

things will be the same as usual.
