Ah, so you are that one guy on the internet that has so many other things to do, nice to meet you!
It is not about time. We have 24 hours every day, everyone has lots of things to do.
If I could read just one or two sentences describing what your code does, I had at least some basic information to consider if it is worth spending some time on this.
As there is nothing and you think it is a waste of time to document that code, why should I spend my time with some code that you think is a waste of time to document?
Anyway, have a nice day!
