If you being in a jail room creates from bricks, if you being enough time on this room, so you give a name to all bricks;

Lulu, lolo, mumu, momo, bobo, kuku, malaka, wakuko, suzuri, wanana, yenunu, etc..

So many people bored of this life, because there are so many bricks in it. So we start naming and labeling things. Unimportant things.
