My daughter has only been in the Navy since March. We saw her at PIR and then flew out to Pensacola, FL to visit her in A School. I know exactly what you mean about the "See you Laters" They are extremely hard. I think it actually gets harder!
my son has been in the navy for 4 years and hasn't been home for the last two. he is coming home next month!!! the "see you later" was getting a little easier. when he leaves this time, it will feel like the first time. it helps me to know he is happy!! there is skyping, which isn't quite the same, but helps a little.lol good luck to both of your sailors and thank them for their service!
