When someone repeatedly misses dialogue, actions, or expressions to the point of not responding to what my character is doing in their replies, even after a gentle nudge towards what I've posted. Eventually it feels like they don't really want to rp with you, just a reflection of themselves.
It's super super rare (and everyone misses something time to time), but when it happens I get twitchy.
