grow up already.

I wonder when people really grow up.

When does it become official?

And who says so?

Is it the said person that grows up who says when is when?
Is it their family?
Is it their friends?
Is it their lover?

Or is it an age?
Is someone really an adult when then turn 18?
19?
21?
Or can they become grown up before they are 18?

Is it all situational?
Or is it the same for everyone?

Is there some defining moment that has to happen?
Or is it a string of events?

I'm just so confused right now.



Some one please help me figure this out. :(
