This new boss was absolutely fantastic. He was shaken by the way I was treated at my previous job, and showed a deep understanding of my very nervous behavior thanks to this trauma, always reassuring me I wasn't doing anything wrong and not stepping out of line at all.
I'd like to think we built a deep friendship along with this job. He's simply an awesome person and I wish him well, even if I know he most likely won't ever see this post.
For the first time ever in my life I felt actually happy to be working. Even dealing with serial ports and printers couldn't cool down my joy at finally having found something that I was meant to do all along.
