I completely understand not wanting to reveal acceptances and FA offers until the process is completed. In this day and age it might be possible to figure out the son’s identity.
I don’t think the poster owes anyone more info than he was willing to give out. He was not asking for advice, just trying to explain how he went about it.
Remember, just because a reader is curious doesn’t mean they are owed an answer. On CC or anywhere in life. The parent set a boundary and I am ok with that.
