5 months as of today... and not a peep from anyone, but I haven't tried to contact them either. I am kind of sad (about a couple of people) and a bit paranoid that there is a specific reason why (what awful things did my former supervisor accuse me of doing after I left? Theft of property or company secrets? Somehow sabotaging the project I headed up? Stuff I never even touched, but got screwed up through his own incompetence? I know, who cares... but he was a total bastard and loved being evil and petty and blaming others for his incredible screw-ups.
I am playing with the idea of going for a visit this month, and I have just recently started thinking of my professional contacts outside of my own workplace (vendors and such) that I could still hopefully use for services if I have a need in the future. But I still end up with a pretty icky feeling in my stomach even thinking about work-related stuff at this point, so I guess it may be one of those things I recheck in a month or two and see how I feel.
