It's possible that it's still listening to you. It's possible that it's not. It's also quite possible that you're in the range of other listening and facial recognition devices that you do not have control over. Always be suspect of TVs in public locations. The other possibility is to examine what brought up the topic of fountain pens. Because these advertising companies have gotten very good at putting together models of thought processes based on completely innocuous and oftentimes data that we don't even consider as relevant. They are able to assemble this into a list of probable things you would be interested in and then advertise that to you. I suggest that as a possibility because oftentimes we think topics are unrelated or they are abnormal and random things that come up but that is rarely so. The way the mind works how it maps data together can seem disconnected in random but it's often not. So those patterns of how the brain assembles memories thoughts and reasoning can be deduced and exploited. So It can seem like you had a conversation about pens that is completely unrelated to any other things you have been doing lately but it may not actually be. The way your mind drove you to having a discussion about fountain pens is simply the same way the advertising companies new to present targeted ads to you about it. I suspect it is somewhat a combination of both of these things.
