I don't know if what I experience is coming from the same reason but I do get something like that sometimes. A recent example, my mom said that I could do whatever I wanted in regards to supper and I thought she was really upset with me only to find out later she wasn't. One of the worse cases was a little while ago. I would tease my brother in law and thought he was being playful back but really he was giving off all sorts of cues that it was really ticking him off. It took a long conversation with my sister to tell me that this wasn't the case. It sure can be frustrating.
