This is one of my favorite xkcd strips, and it really says all there is to say. But it reminds me of something else I see a lot, which is complaints about selfies, pictures of food, etc. and sharing them to social media. People ask "who cares?" and say the photos will be gone within an hour and no one will remember them.
And this is weird to me because I think people should care. You check in to see how they're doing, see where they've been and how they look. When people share little bits of their personal lives with others, why not care? That's what friends do. They care about the random fun things their friends are up to. It's always been that way; the only difference is that instead of someone sharing stories about the great meal they had or the outfit they wore one night and really liked, they can show you instead.
There's so much concern over the way people enjoy themselves and share the things that make them happy, I have to wonder if getting pats on the back for deriding kids these days and their silly habits is more important than just enjoying stuff. Or at the very least ignoring the things that bother you without incessant negative commentary.
