So you have a bus or train ride. One that you do routinely enough, and you are well aware that by the time you near your destination, it is likely that the bus or train will be 80% full. You got on early, and have a seat to yourself. How do you keep your morning thoughts and avoid an unwanted seat mate?
Some people set up a laptop, and stash the case on the seat, hoping. Others carry a porn magazine (effective but creepy) to “read” on the train.
Now what headphones could you wear to discourage fellow travelers? After a few suggestions we can have a poll.
