Maturity

I just reread my post from yesterday. Is it bad that I still giggle when I call people smelly? Should I have grown out of this by now? Should I no longer find the words poo, bum, wee, willy and boobies funny? Will it mean that I have finally grown up when I fail to crack a smile when someone says Number 2? I think I just have to face up to the fact that I am immature and may stay this way for a while. He, he, he, boobies.
