Nervous Nellie

So, I got the job that I was interviewing for a while back.  It's been an alright gig at this point. 
I'm working with Ashley right now, which I was a little wary about, but again, it's been okay.  We did stock the other day, and the two of us got super fast at getting stuff done.  She would open the box, and I would pull out all the packing stuff (in this case, mostly that brown paper they wad up).  Then she would go through the inventory checklist and I would move the stuff onto the storage shelves.  If there was extra still, she'd move those products too.  And then whoever had their hands free next went to get the next box, and we moved all over again.  We were very efficient, and I was happy as a clam.
Out on the floor, things were not so simple.  I'm struggling to learn the cash register.  Certain things were never taught to me and other things are just confusing.  My superior told me not to be nervous, and that made me feel bad, because I honestly don't feel particularly nervous.
Interacting with the customers went very well.  A young woman who worked at the caf at school came in, and I jokingly said that I visited her at her workplace, so she could visit me at mine.  And then my Mom and sister came in. 
Later on, a woman with four young girls came in looking for a game.  I sold them a game by American Girl called I Wish.  One of them cried a little at not getting something else, but there are occasionally tears around here.  Parents usually handle it, and it's okay.
