I use the tree c:\ command when computer illiterate people want to watch me fix their computer.
Is there a problem with using that command?
No, there's no issue with the command, but I always ignore them when they talk to me while I am fixing their PC.
You are being helpful by fixing things for these people, but I feel like there's a better way to go about doing it.
There is nothing you can do about it anyway.
I feel if you are more kind to the people you're helping they would be a lot more appreciative towards the work you're doing. Being understanding and compassionate towards their problems would make for a better situation with them and end up better for you.
