For the past four months, I've been writing back and forth with a friend of mine in a form of roleplay. Depending on what's happening, our replies range from a few sentences (usually with dialogue) to a few paragraphs. While I've gotten much better at writing and understanding my main character, I've begun to notice how I always seem to fall back on the same structure, the same verbs, etc. Here are a few examples:
He leaned into her touch, watching her with a content smile on his face.
He gritted his teeth slightly, pouring the hot water into his cup as he felt his cheeks heating.
He raised an eyebrow at her, before slowing his pace a little, moving to step by her side.
His breath caught in his throat, and he coughed a little, looking away.
He held the door for her, allowing her to pass through, before moving to follow her.
Now, what I'm mainly pointing out here is my habit of starting with either my character's name or pronoun, my tendency to use a comma followed by a verb (sometimes multiple times in the same sentence, and my repeated use of phrases or transition words such as "moving to [verb]", "before", "and he", etc. I do often write small notions about what's going on in my character's head, but that's not applicable for every single reply I write.
It's been driving me crazy, but I often don't know how else to word/structure certain things. The nature of roleplay already puts me into a position where I can only write things my character is doing, saying, thinking, or feeling -- is this a natural consequence, or could I be doing more?
