Teamlead: Can you integrate feature X to project Y? The dev maintaining that project has lots of work and does not know how to do it, and we need to deliver it next week.
Me: Sure, I know that feature should not take long.

BIG MISTAKE!

For 2 hours now I'm trying to get that fucking project to run... errors, faulty configuration, tons of missing stuff in the project environment.
The list of errors grows with every step I get further. And I have not even started with the feature I should work on.

So good luck next week, my dear colleague, I'm not the one finishing your tasks from the past few months, I'm just fixing the stuff I actually need to finish my task.
