I have been on both - actually on all three - sorry, make that four - sides.

1. I tried to ship crap and complained to my manager for being blocked. I was young, dumb, in a bad place and generally an asshole. 2. I was the manager being told that some unreasonable idiot from X blocked their progress. I was the unreasonable manager demanding my people to be unblocked. I was without context, had a very bad prior relationship with the other party and an asshole - because no prior bad faith acts were actually behind the block - it was shitty code. 3. I was the manager being asked to help with unblocking. I asked to understand the issue and to actually try to - based on the facts - find a way towards a solution. My report had to refactor. 4. I was the one being asked. Luckily I had prior experience and did this time manage to not become the asshole.

I am glad I had the environments to learn.
