Get your license in, foo

I substitute teach for a local school district.  The last few times I taught it was VERY apparent that I am visually disabled.  I was able to do the job fine, but any reading (especially rosters for attendance) make my issue very obvious.  Well, since about December I stopped getting calls for jobs. Here I am thinking that "oh, someone must of said something about my OBVIOUS problem and they don't want me anymore".  Yesterday, I called the district about their new automated system and how I am unable to get logged in. [Here is a clue, they were still sending me correspondence, maybe, just maybe I have the story wrong]. While the gal is helping me with my log in issues I naively ask "Hey, I got my renewed license because my last one expired in November, do I need to take that down to you all for a copy on my file?"  These were not her exact words, but in essence "Uh, duh!"  I got a call later explaining that I wasn't able to log into the system because I had been put on inactive, NOT because of my vision, but because I hadn't gotten my renewed license to district.  License is in, I can log in, and calls should start coming again.  Wow that was totally worth stressing about, NOT!
