Bubble Bursting

It amazes me how people can go on with their lives so oblivious to the facts and events around them. How they can be completely unaffected by things- trivial things, big things. They all seem to glide on past them without a second glance. Is it calousness? Or is it a defence mechanism? I used to be like that- clueless, oblvious, not a care in the world. Things would always turn out right. That was oblivion. Now it's my defence. If I start to think about all that's going on- the trivial and the not-so-trivial, I would literally explode. My world isn't rosy anymore and I don't have glasses tinted dark enough to hide the ugliness so it's better if I just close my eyes...
