Stupidity

Stupid people are just people who don't bother learning anything to better themselves. They don't care about grammar or speech, so then they sound stupid. They don't learn very much, so all they can do is basic tasks, but don't have any real professions (most of the time). They usually work at simple jobs like McDonalds, gas stations, and other fast food joints. They never cared enough to improve their level of intelligence, or focus on learning something that mattered.

Stupid people = People who could be smart, but don't bother to be.
