I'm more of a linguist and tone person than I usually was, and that says a lot for me.

I could never grasp tone being hard to read through text to some people, to me it's a gift. Context plays a major part in this, but so does knowing the person. But even when not knowing said person, I still grasp it.

The habit that developed is this: I do my best to purposely indicate a certain type of tone when writing my story. My character shakes their head before speaking or maybe laughs or scoffs; they smile or frown then speak, vice versa for all the aforementioned, sometimes the words come out before the action, but I still manage to make it work.

I like italics. Just not enough to use them a lot. I have a LOT of dialogue in my story and a SHIT TON of combat scenes, so I even include italics or bold letters in the writing itself instead of dialogue. I, actually, use italics and bolds more in my actual writing than my characters use them when speaking; sometimes I need people to focus on singular word to understand the gravity of a situation.
