your character is doing their own thing, we recommend that you start your own open thread instead to follow the scenario you have in mind.
react and add an action. when replying to a thread, the idea is to add to the scene and push the thread forward. to do this, you want to both react to what the posts above yours did, as well as add your own new action for posts following yours to react to.
an ideal post will have both a reaction and an action, or else you risk one person being forced to drag the entire thread forward on their own, which can be frustrating for some.
