Must confess that graduation week was one of the best times of my life. USNA makes it so very special for every grad and their family. We went to almost every "official" event and quite a few non-official ones. It's a week that just builds and builds until that special moment of graduation / commissioning.
For soon-to-be-grads, keep in mind that this is likely the last time your family will see you at USNA. Even if you aren't excited about the band concert or church service or Supe's garden reception or dances or whatever, your family probably will be. This is their big chance to celebrate with you and -- in most cases -- you owe a lot of your success to your family. Graduation week is about you, but it's also about them. Let them enjoy!
For parents -- notwithstanding the above, rein in your desire to do everything. Your mid is ready to be done, to embark on their new journey. They want to spend time with their best friends, some of whom they may not see for years and some maybe not ever. They're tired of King Hall food, trips to the MidStore and dances in Dahlgren. Cut them some slack if they don't want to attend every event. Pick the ones that are most meaningful to you and be willing to forego some of the others.
Most of all, enjoy the time together. Enjoy the accomplishment. Enjoy the future the lies ahead!
