Growing Up

I really do hate growing up.
Ok this popped out after a string of events happened last week itself.
People who 1st befriended me usually says my attitude is childish or immature. I would never ever doubt it cuz i am. Then after a certain time or duration they would suddenly say that "Oh, you are so mature, how did you do that?".
Haha seriously. Thus i asked them to define being mature, they answered me a very complex answer, "Being mature is to know life itself, and being mature is doing what adults do".
Haha i was stunned by their answer as i never thought maturity is being seen or viewed sooo CHILDISHly.
Hence, they asked me the same question, and i answered "maturely"(hahahaha), "Being mature is simply being able to enjoy life as how u want it to be, What's the point of knowing life but not knowing how to live it ".
So i told them a child acts adultly while an adult acts childishly, its the way of life its called growing up.
"A smile can do wonders". It can rubbed of the most painful memory and soothe the heart, so why not smile , laugh, be happy all the time rather than frowning acting MATUREly. Just go crazy but always have a limit.
Then they asked me how to know u are enjoying it. I answered, "Act according to the situation and try to adapt quickly", as no matter how u wanna to enjoy, in life there are rules neeeded to be followed.
For example, a function requires formal dressing, you wear formally, be obedient but by any chance just be yourself.
I'm not saying adults acting cool are not mature, they are but only in their on context don't let it influence your principles like me.
The most painful thing is to see someone close to you, lets say a child growing up no longer acting happy go lucky, they care for everything happening around them and tends to act all grown up,(haha), slowly creating a distance or a small gap with you as I know for sure if I'm the grown up the child will not even talk happily with me anymore when she reaches her teens.(well i ain't cool enough)
I really hate this growing up thingy but LIFE's a bitch.
