That's actually a question I've always had on my mind, I figured it wasn't like, something that came right off of the dome, but what drives you all to do the quirks to begin with? Is changing things up over time seen as a natural thing or something taboo?
To answer your question, do you think it would be more interesting mixing it up like that? You're the one who'd have to type it out.
⚘ can't really speak for every troll, but ⚘n my case, ⚘ go off of how ⚘ feel about myself. ⚘t sounds dumb, but ⚘ put l⚘ttle flowers ⚘n my text because ⚘ feel l⚘ke ⚘ grow and change a lot l⚘ke one. ⚘ don't see why ⚘t'd be taboo for anyone to want to change the⚘r qu⚘rk, ⚘t's just how they type.
As for the other quest⚘on, ⚘ really don't know... maybe ⚘t'd be more fun to type l⚘ke th⚘s?
