mkdir --verbose my_friends

If you type ls -l You’ll see it there along with information about it.
Now you know how to use ‘mkdir’. You can even use it to create a directory called ‘my_enemies’ if you’re into that sort of thing.

Linux would politely tell you that you can’t do that.
So, you have to use your ‘rm’ command on the files first to remove them or use ‘mv’ to get them into another directory. Then you’re free to use ‘rmdir’
