I was fortunate and saw Dad more than rarely, though he was gone TDY twice for 90 days and Remote for a whole year while I was young. These reunions are good to see.
My Dad was in Korea. I didn’t see him from about the age of 18 months old until I was more than three. He also spent 2 tours of duty out of the country when I was about 5-7. It is a way of life. No email, cell phones or skype back then.
