I was supposed to just review the PR. But I couldn't stop myself from making minor changes.

It has been 4 hours now. I'm thinking if I should raise a PR for the PR.

So who will review the PR reviewers PR?

Well, yeah! All joking aside, that's exactly what you should do:
- shelf your changes
- approve their PR so they can have some peace of mind
- then immediately raise your own PR
But I'm telling you what you already know... right?

@hamido-san I know that... But didn't follow it this time

As a reviewer, add comments and ask them to fix stuff. Until then, the PR will be in "requiring more changes" or something

You should stop yourself from **adding minor changes*** in somebody else's PR.
Why don't you add comments, have discussions on what can be better and how. Let them finish what they have started. Help them grow, teach them, learn from them. Be a good colleague/senior.

Or work alone

A PR is meant for reviewing.

It's a reviewers job to comment, not to work on the PR.

And a PR should never be merged unless it is fully baked.

Quick ejaculations lead to major frustrations.
