Immaturity...Good or Bad?

Definition:
Immature- emotionally undeveloped; juvenile; childish.
Mature- emotionally developed; adult; grown up.

On a scale of one to ten, how immature are you? Is that number necessarily a bad thing?
People view immaturity as being frivolous all the time, and maturity as being serious all the time. But, it's not whether you're mature or immature...you can't exactly be one or the other. There is an in between.
In my opinion, there are times to be serious and times to be frivolous. Adults can't always be mature, that gets boring. Who would want to be serious all the time? There are times that you have to let your hair down, get away from the seriousness of everything and mess around in a completely juvenile way.
And as for the "childish" adults...they can't just play all the time. It gets extremely annoying. Not just to the people around them, but to themselves as well.
Nope, people are in between. The in between may vary from three to eight, but that's normal.
There are times when people act a certain way in the wrong situation, but, my theory on that is, they don't really know what's going on, or they're just too nervous to know what to do so they do the first thing that comes to their head. It's not a bad thing, it's instinct. It just gets embarrassing.
