The case in particular I remember from personal experience a few years back was when I was wearing a navy blue USAA shirt while overseeing the USAA team handing out freebies to parents. A mom came up to me, and I realized she thought I was a USNA official. She pointed out her daughter, who had a phone, folder and small tote bag in her hand, saying she had insisted on her mom driving her 4 hours to I-Day in case she got a call from Admissions and was offered a spot. Mom was clearly upset by it all as she watched her daughter lingering outside Alumni Hall. There was only skeleton staff in Admissions, of course. Mom said she thought it best to let daughter go through this, because she was so set on it, focus on recovery and next steps tomorrow, but her heart was breaking for her DD. I happened to see a chaplain I knew, and I waved him over with a quick explanation. God bless Navy chaplains, he sized up the situation right away and took mom and daughter in tow and into Admissions for a quiet chat. He told me later he found one of the Admissions LTs to give the candidate some closure and tips on re-applying.
There is some date before I-Day when the class size is truly gelled, with no more planned puts and takes. The class size will fall within the target range, and subsequent attrition will be relatively predictable.
