asking about minor details in the wording of the title of this thread, which I found weird.

Gee, you didn't find it strange? /s

It's not minor. Your comment was minor, yes, but mine was not. But is actually intended to bring up the point in in Western culture, it is not typical to refer to adult males as "boys," but that it is is typical to refer to adult females as "girls." This is likely caused by the fact that males have to "prove themselves" as "men" or some other such nonsense stemming from eras past in which young males had to perform some sort of physical task before being permitted to go on hunts with the other males.

This has permeated into the present day with things like "bro-hugs" instead of "hugs" and "man-bags" instead of "purses," because these things, apparently seen as typically used by women, need to be made "safe" for men to use. That way, they can retain their apparently hard-earned "manhood."

Long story short, since females (in the eras past and today) don't have to "earn their woman card," if you will, there is no problem with calling them the more youthful term of "girls" but, as is usually seen (and is the case of OP), the males aren't called "boys."

If you aren't familiar with this phenomenon, I suggest at least a freshman-level psychology course in gender and sexuality or whatever your local university offers.

I find this subject fascinating and therefore brought it up when there was a relevant situation to do so (in this case, OP's use of terms). You could even know that I find this subject fascinating, even though you claim it was not possible here:

It was not possible to know which of those you meant before you told me.

Because of my very first comment in which I said, "I'm more interested..." That should've been a dead giveaway.

So, unfortunately, you considered my comment a "minor detail," falling to the lowest common denominator and then made, by your own admission a comment about a "minor detail."

I think at this point, we can go ahead and note your comment as "commenting on a minor detail" and note my comment as "commenting on a gender-based phenomenon" and we can close this conversation.
