Even better when you get the same questions from family the few times you can see them over the holidays or between PCS.
One of the common misconceptions is that when you're in port you just shut it all down and take vacation.
It's gotten to the point where I just avoid talking about it rather than explain the same thing for the 5th time.
I've got a cousin who's got similar misconceptions. I was deployed through Thanksgiving and Christmas one year and so our family put care packages and whatnot together for me. She apparently complained the whole time about why it was such a big deal that I was gone and why everyone was making such a fuss about it. She apparently thought it was having the time of my life at sea like I was on some cruise ship or something. She couldn't comprehend how much it sucked at times and how busy I actually was.
The odd part is that we come from a military family and her own father -- my uncle -- was in the USAF and Air Guard. It probably didn't help that the only times I got to talk to the family were when I was in port in places like Italy, Greece, Malta, and Spain.
