oh i’m not making fun of tone tags in general but just this instance
but the tone tag here isn’t necessary, since like you said “People would be able to tell that they’re not in 2048 because that’s not possible”
but someone might not know that you're joking and could think that you're genuinely confused (i think that's @mybearworld 's point)
That I’m joking? I know what tonetags are and that they are helpful non some contexts but aren’t here (people should know you aren’t in 2048 as time travel isn’t possible), which is what I’m joking about
people might not know that @KuromiNotTaken was joking. (they might think that @KuromiNotTaken is confused)
