The life of a grammar Nazi is a lonely one.

Finally! Another one of my people! But what does "grammar" mean, if you don't mind me asking?

grammar
/grăm′ər/
noun
The study of how words and their component parts combine to form sentences.
The study of structural relationships in language or in a language, sometimes including pronunciation, meaning, and linguistic history.
The system of inflections, syntax, and word formation of a language.
from The American Heritage® Dictionary

Grammar NAZI is a little far... how about Grammar Care people?

Whatever you prefer is fine and I definitely agree that grammar is important.

Yeah. I agree. Upvote to you!

And back at you! I am glad to see a young person supporting proper grammar. Never forget that you will be judged by the way that you speak and I applaud you for your sentiments. Carry on...:)
