If you're an adult and act like a child, then you better get some help.
Is it alright to be an adult but act like a child?
It'd be kind of embarrassing if an adult acted like a child all the time... Imagine if adults threw tantrums every time they didn't get their way!
Like this lady who looks like she's crying because someone took her parking space:
Having said that, I think it's good when adults can still remember how to have fun and laugh like little kids. I love playing with my daughter or taking her to the park because it's an excuse to act like a big kid for a little while.
Speaking honestly... No! It isn't okay for youngsters to act like children either, but I think it's okay for adults to act like youngsters!
