The most difficult part of being deployed "back in the day" was waiting for the next letter, which could be weeks or months. I stood in line for 8 hours at a pier in Buson Korea to use the ONE phone that was available. Difficult to way to find out one's father has ALS and not long to live. Today's generation can not conceive of such "delay" for information. When my Marine squadron was deployed aboard ship, I heard the phrase "There are no tears beyond the pier." Today, it must be, 'how long will we have internet, beyond the pier?'
