Back when I was a teenager, I used to also have similar thoughts as the person you replied to about not playing with toys because it was childish behavior.
Luckily, I grew out of that and I do not feel self conscious when playing as an adult or being goofy.
>To carry on into middle life or even into early manhood this concern about being adult is a mark of really arrested development. When I was ten, I read fairy tales in secret and would have been ashamed if I had been found doing so. Now that I am fifty I read them openly. When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up.
