As a university instructor who does a fair amount of these Zoom classes,...I would be a bit taken back by your lack of interest in class you are taking,...and likely paying for,...because you saw someone with a NASA shirt and wanted to "reach out to them" by playing NASA TV on your video feed. This is not the time nor the situation where that would be acceptable. As you mentioned,...you've interrupted the class. According to your profile age, you're 24,...not 12. You're taking a class with adults.
Furthermore, I can empathize with your lack of "cognitive empathy" and lack of "theory of mind",...it can be confusing trying to understand the social language of neurotypicals. What is socially acceptable doesn't always make sense,...I've tried,...I am 53, work with the public,...and still get perplexed by it all. It can lead to some thinking errors,...which others have pointed out to you on the above posts. Right or wrong, I have learned to keep my natural impulsive nature at bay,...forcing myself to keep my mouth shut,...and then, if possible, ask appropriate questions to gain some more context before firing off comments or making judgements. That, in and of itself, takes a bit of self-discipline,...and it is not easy.
