It took me a long time to become aware of and to try to break my habit of saying whatever (usually negative) thing that comes to mind. After spending a few days on irc, I realize having grown up on the internet is where I got that habit from, because 99% of people respond with something negative on irc to just about anything. Luckily the sentences are so short thanks to irc that it's easy to just ignore and not get roped into. But it's funny. I guess the negativity of the internet is just a universal thing.
For example, I saw some people quoting Nine Inch Nails lyrics, so I said, "nin is so good, I saw them live a month ago, great show," and one person responded, "reznor is old asf, probably doesn't hit as hard."
I replied, "he's still got it, thank goodness. everyone's going crazy over the nin Coachella performance." Another person chimes in, "i looked over someone's shoulder and saw trent reznor with many backup dancers and it did not resemble what i remember as nine inch nails... but that is fine."
So, yeah, just because people are talking about something they like, the second you chime in to say "I like that thing, too!" suddenly no one has anything good to say about it.
