It is not polite to shout on the internet. When you use all capital letters you are considered shouting. People tend to do this because they think what they have to say is more important than what others have to say. Or maybe they just don’t want to go all the way over to the Cap Lock button, it is such a stretch. You mite just get carpel tunnel. So unless your are worried about your health STOP SHOUTING!
Side NOTE: All these years you thought your cat was saying me-yow. When they have actually been shouting. ME-NOW ME-NOW ME-NOW.
