I hate the injection of personality into technological instances or common hiccups in modern Internet culture. My heart monitor watch shows me a smiley face while booting up, Github buttons spam "Buy me a coffee!", Reddit says shit like, "Don't panic" when a webpage doesn't load. Shut the fuck up and leave me alone. I am so tired of being surrounded by these pale imitations of reality, like I need to be pacified with pseudo-emotions or meme culture every step of my day.
I can only speak for myself but the reason I say "I'm fine" is because I figure the other person is only asking to be polite and doesn't really want to hear about my problems.
