How do you say goodbye to a new friend

The mean coldness shackles your arm,
As you speak, a certain barrel mutes your voice,
You hold your breath as it goes away,
Watching it fade, just right after it arrived.

The hour peaked to the time where things should end,
But for you things have just started.
You seek for understanding, you seek for extension,
But you could only ask for them in the form of illusion.
