all grown up

i remember reading the following saying in a book when i was eighteen years old . 'you can never go home again' meaning once you leave home you can never go back to the way it was. as a young adult that meant being independent when i was out of town but when i visited my parents it was hard to still be the kid.
time passes and the meaning of this proverb changes.
eventually you find a job , friends and  perhaps you marry or  have children. you busy yourself with the things that are important to you.

one day you visit your immediate family and then you realize that though you love them very much you have a life that is very separate than theirs and that  you miss that life tthat you have created when you are away from it. suddenly you realize that you are all grown up .
