Attention can make one focus on one thing and distract them from their surroundings. For example, I’ve personally experienced this. This happened in June. I was on my way home, meanwhile I was in an argument with my friend through text. I was very focused on the conversation. As I got into the bus I took a quick glimpse to see if there were seats available. As soon as I get in a spot on the bus I receive a text from my father. It read, “look at the back of the bus.” I quickly turned my head and see my father sitting down. I didn’t notice him at all as I was focused on the argument I had with my friend.
