I wonder how my replacement at my old job views the work I did there. Spending several years at one place as a one-man department, you tend to make the quirks and inaccuracies in your network, and the band-aids you apply, effective and efficient. It works for you but wouldn’t work in a multi-man department or for anyone else, including the replacement.
I find myself facing that issue here. I’m constantly saying things like “Why would he do things like this?” “What was he thinking?” etc. I bet my replacement is saying the same things. How easy it becomes to badmouth and blame the other guy.
