Because younger people are dumb shits and are confused easily?
Plus fuck their vocal fry, the little assholes.
I use ellipses formally all the time when leaving out portions of statutes or legal regulations.
I think they can be a nice tool to imply some space before a punchline or an idea. I use them informally when I want to convey a greater sense of trailing off in thought or time than a simple period would show. Or if one wants to state a conclusion that has a slight chance of proving to be untrue.
I realize in a text message, if someone asks me how something went, I will tell them and it it with a period.
If they are asking me about how a game is going and my team is winning, I will admit I'm more likely to say "Texas looks pretty good so far, but only have way through the second...." to me represents a more interesting visual to accompany the idea of not knowing how things will turn out than if I just used period.
Yeah, the aggies look pretty good this year...for me to poop on.
I grow old ... I grow old ...
I shall wear the bottoms of my trousers rolled.
