When the mind is single tracked

You know that person in the grocery store who goes up to the sample tray and parks their body physically in front of it, so that you can’t reach around and grab one yourself? The person who is so singular in mind that they lack the wherewithal or simply don’t care that there are people behind him or her who might be trying to get at the same thing? That is the same person who will put on a pair of headphones and try to communicate with others by shouting in order to hear their own voice. Taking no recognition of the fact that the music is strapped to their own earholes and not everyone else’s. You would think that people might have enough experience talking that they don’t need to hear their own voice in order to operate it. This is also the same person who has no skill in the ability to multi-task. Their thinking is so linear that if you introduce a new concept while they are trying to perform one simple task, it all ends in a smashup.
