Context: I have received a feedback request for an interview process. The company didn't offer me the job, but I appreciate their approach in requesting feedback, so I am inclined to provide it. However, I'm not sure it's anonymous and I'd like to express some criticism, but I also would like to not be excluded from a possible recruiting process in the future because of my opinions. I told someone the following sentence:
I am reluctant to express negative feedback to someone whose door I might knock on again in the future.
They (native speaker) corrected me saying:
... whose door I might cross ...
Which version do you prefer?
