Anyway, i realized something when i was on cab to work on Tuesday, 11Jan. And i think i came to a conclusion for that. This is what i realized:

Try taking something small. Even lifting up your hand. And place in front of you. Turn one round and focus on the small thing you are holding or your hand. Did anyone realized that, things behind is covered by your hand or the small objects you're holding? Did anyone get it? Okay. Put it in another way. For example, there is one bottle in front of you, say, height 40cm width 15cm. You stand far away from it and then lift up your hand. Now, this bottle is "well-covered" by your "big" hand at the place your standing. Try walking nearer one step at a time. Realized the bottle gets "bigger"? 

What am i trying to do with this "only kids will do" things? (Okay, probably kids nowadays also not as bored as me.) When one stand away from the bottle, they acknowledge the bottle existence, but yet deny the fact of its actual size. Imagine the bottle represent individuals' problems in life (work, relationship, family, money, studies etc). 

It's not that they never acknowledge the problems, but rather, they "cover" it well so that they will think that the problem is not a very big issue at all. Good and bad to have such mentality. I mean, at least probably they are on the way to solve that problem that is why they don't find it as a big issue. If that is the case, how about the other group of people who didn't do the same?
