I think it all depends on how we live our lives. I like to go out dancing at clubs every once in a while and some people would call me immature for liking to do that because I will be 40 but then again, I see 60 year olds at clubs just having a grand time. So, does that mean, I should be sitting on a rocking chair on a Saturday night for the rest of life because I am 40 or because I am a teacher? In my opinion, no but if others feel that is how their own lives should be, then kudos to them.
So, I let certain people label me as immature but as long as I am out and having fun, it is all good.
As for name calling...ok that is a different story but what does having a college degree have to do with name calling? That was where my questioning and theoritically speaking came in.
