I dont want to grow up

It happens to all of us we wake up one day and realize we are adults- although I have decided that is not much different then being a kid. Yes there are more responsibilities, you know paying bills, getting a job, but ultimately I think that is it. I feel like that all adult issues can be directly compared to children's issues.."it's my toy- so you can't have it"...."My toy is bigger/better than your toy"..well " he/she hit me first"...I mean stop and think about it...we never really graduate..we never really grow up. The issues we deal with as children and teenagers seems to haunt us for the rest of our lives. We always fight to find ourselves among our friends, co-workers and families. We struggle with our self image, self esteem and trying to fit in with some group- maybe not always the "cool" kids, but a group none the less.  We still struggle with trusting ourselves and our decisions. We still deal with bullies and may even find ourselves being the bully. I personally struggle with finding my big girl voice, I think we all our scared children inside our big adult bodies. I find it hard to stand up to people older than me and to stand my ground. I always feel like I am being judged because I am the younger one, I feel a lot of people see me and assume that I am young that I couldn't possibly understand. See? Again we always feel like a kid and in reality we will always be a kid to someone. There will always be some one older than us that assumes we are too young to understand. I really hate it- It seems no matter how strong I get there is always somewhere that (I let) strike me down. I will admit a lot if its on me, on us- we have to rise above, but it seems harder when the person is older or more established that us. How do we respect our elders and when do we stand on our own and understand we are on the same playing field?
