i have two modes of typing.
One is where I use (mostly) proper punctuation, grammar and spelling, as well as proper capitalisation. I make sure that if I nest a quote inside speech marks, I use ' blah blah ' rather than " bleh " again so it's clear what's going on, and so on.
the other is where i literally stop giving any fucks like lol :D
filibustering the timeline with my garbage
generally I consider the "proper" typing method to be like...
i dunno...
more Serious?
but for the most part I don't bother when I'm being conversational or silly.
honestly when I go full pooptoot i often leave out any capitalisation, grammar, punctuation or anything at all let alone full stops because I gotta get that entire pooptoot out as fast as possible before someone has a chance to stop me :3
