It's a phrase we hear all the time. Usually when someone says that, they mean, "Quit being so immature."
Sure, there are some things, like throwing a tantrum, that are unacceptable. We aren't perfect. Far from it. But there are other strings attached to supposed immaturity--good things. So what does it really mean to be mature?
Does it mean giving up things you loved as a child--like stuffed animals, popsicles, and sidewalk chalk?
Does it mean you can't get excited about things like Pokemon and shiny stickers?
Does it mean losing your sense of adventure, your love of imagination?
Does it mean being serious all the time?
Does it mean giving up your dreams?
I've lost a lot of things over the years. I've lost the innocence I once held. I've lost time. I've lost friends and family. I've lost pieces of my music and art and writing. There are also some things that I'm glad to be rid of. I've lost the hatred I once harbored. I've lost my fear of making new friends. I've lost much of the anxiety of sharing my feelings. I've lost my ability to purposefully hurt another person. I've lost many of my inhibitions.
But I will never lose my sense of wonder. I will never lose my love of people. I will never give up my dreams. I will never stop writing.
And I will never grow up.
