ME - me, TM - teammate
I was just recruited to the company. We're starting new project based on few modules.

ME: So this module will do X and Y, I will use good old interfaces and design based on abstractions so that stuff does not get glued too much.

TM: But why? Make good old processor with all the logic and throw objects at it.

ME: B-but unit tests, decomposition and othet stuff...

TM: *insists and forces me to agree*

ME: *gets shit done his way, TM checks on code review and complains but generally doesnt give a fuck*

ME: Ok, its done. Lets get shit shipped.

TM: Well, we were just told by PM that we will need to process one more source with much different logic that does not fit current solution (he did meant GOD-PROCESSOR, idea of his).

ME: What do you mean? *injects another contextual implementation of processing logic to template method pattern solution*.

TM: I will tell PM you cant make it because of the implementation.

ME: But I just did it...

TM: Impossible, processor needs to be reimplemented. Get your shit together!

ME: *still doesnt get the shit about the god processor love*

TM: *rage quits next month*

ME: *module gets reused once more 2 month later, profit*
