Childish irony

It's raining, it's cold outside and we're eagerly waiting for the traffic lights to turn green.....again and again and again.... Everybody in the bus is thinking at something/someone, there's an awkward silence surrounding us. The bus stops, three kids hop in and start laughing. They laugh so loudly that everybody stopped thinking for a second and decided to give them "the look". You bad kids!
At the same time you realize that you stopped having that innocent fun, the childish one, and you wonder why. A first thought comes to your mind: I am a grownup now, that's what grownups do. We have to think about tomorrow, about tomorrow's deadlines, about the daily chores, if we payed our bills or not and so on, thus there's no time for fooling around! What were you thinking!?!?!
Isn't it ironic? When you're a child you want to grow up, be a part of the adult world because it's so cool. You think that nobody will tell you what to do, that you'll be able to do whatever you feel like doing. And then, it happens! You're a grownup.

Let's go in the park and have an ice cream!
No,you can't because you have a very important deadline tomorrow!

Do the first crazy that comes in your mind!
Grownups think before doing something, come on, don't be a child!

Walk through the rain!
Are you crazy? You can get a cold!

And then you think ....what happened to I can do whatever I wanna do? I wanna be a kid again!
IRONIC, isn't it?
