Patience...can't wait for my patience to kick in!
Yes, patience is the key word here. Most of those who have received appointments thus far are LOA recipients. Those without LOA are starting to trickle in. It also appears that these are "early bird" applicants, had their applications complete at or near the beginning of the cycle. As the saying goes the early bird gets the worm, but in this case the early bird merely gets the first worm. From what we gathered here on this forum, USNA admissions, two visits to Annapolis, one CVW, BGO, military friends, former grads, etc., the majority of folks will find out from March thru April. Remember, not all applicants are active on this forum, so while it seems like a lot are hearing good news, with less than 50 currently listed on the appointment thread, there are a lot of spots left to fill.
You sound like us, DS seemed to have the patience of a saint while Dad, stalked the forum and the mailman, kept Mom in the loop and tried to look cool as a cucumber in front of DS. When the BFE arrived we all went loopy for a while and have now settled into allowing DS to finish high school with a healthy amount of fun while maintaining the performance that got him where he is now. We have been fortunate to have friends with USNA, USMC, and USN experience to keep us sane along the way.
Best of luck to your DS. Prayer also helps when patience is at a premium.
