But...

if you type in "cd $HOME/Documents", you will still get the same results
as doing any of the following:
        cd /home/<your username>/Documents
        cd ~/Documents
        cd /home/`whoami`/Documents
        cd `echo $HOME`/Documents
        
and probably dozens of other combinations.
