When Joyce is talking to Victoria about her father. She says when her husband was in Vietnam she would put tennis shoes in the dryer and sit on it. But since Molly is known to be thirty years old. That would mean she was born in 1985 which would that he would have been home at least ten years before Molly was born. And it would probably have been longer than that since there were only a very few special forces and Marines left after 1973. For two people who had been apart for so long it would be unusual for it to take that long.
