As we all know, 18-21 is usually the age that people are defined as "Adults"
As they are now "Adults" they are allowed to Drink Alcohol or Gamble at a Casino, Legally allowed to have sex with other "Adults" and what not.
Now I would like to know what exactly defines an "Adult" and who decided that age 18-21 defines an "Adult".
In my eyes an "Adult" is a person who can handle themselves well in public, be smart enough not to overdose drugs or alcohol. Not Be Racist. And overall just have good manners and common sense.
I don't understand why Age describes adulthood. I don't want to toot my own horn but I find myself with more manners and common sense than quite a few adults I have met.
