How do you react when someone answers a question by simply rephrasing your earlier answer?

Is your initial response to think this happened unintentionally because they did not read all the responses to the question before posting or do you feel sort of annoyed. I’m not referring to answers that agree with yours in essentials or contain the same or similar information, but those where someone genuinely seems to be copying your answer and merely paraphrasing, long enough after you posted it that you weren’t writing it at the same time. Do you think this happens more with newer Jellies? Is there an unspoken Fluther etiquette in this regard?
