Do Not Touch

"Do not touch this machine unless you have been trained on how to use it!"
Well, I got trained how to use it today! On my second day volunteering at the ACS, I can now officially stamp the mail myself with this fancy machine. I guess my returning was a positive thing, because so many more people came in and introduced themselves today. I had conversations with a bunch of nice people and they all thanked me for being there.
It's going to kill me to do it, but I have to tell them I can't volunteer more than one day a week :( it tires me out so much and with all the work I'm already not doing, I just don't have the time to commit another full day to this.
Sigh.
