So today I was having this discussion with my colleague regarding a messed up pull request.

Me: are you done merging the remaining branches into master?
Colleague: no, I'm still merging the changes manually.
Me: but why?
Colleague: because the changes will overwrite the changes in master.
Me: but how? It will just conflict and you can keep whichever changes YOU WANT. You can even edit before committing the merge.
Colleague: I'm just redoing the changes manually anyway.
Me: -_-
