I just couldn't the rest of the day today, I broke.
I was asked almost immediately this morning to help diagnose and solve a problem that I solved and pointed out 2 years ago. I printed out the drawings, highlighted where appropriate, made notes, printed out my email about it from two years ago, handed it to my boss, grabbed my keys, and left.
What do I do now? Do I go back tomorrow and go back to work? Do I go in and give him my 2 weeks notice? Do I just tell him I'm done and someone can collect my personal stuff from my desk and ship it to me?
