Your comment is unique. Nobody before you has ever written a comment phrased exactly like that.
I saved a copy of your unique comment on my pocket supercomputer, including the letter "a". I didn't ask first; I just did it. It's fine because it doesn't really exist.
Now it's my comment.
exactly. delete all of the "a"s from your comment. what happens to theirs? nothing. because they're not the same thing.
