My son is 33. He does try to call once a week now. When he was in high school he joined the army, and stayed in for 11 years. He now lives several states away, and ever since he joined the army we are lucky if we get to see him every couple years. It is still like that even though he has been out of the army for 5, or 6 years, but he does call. Empty nest is a big bummer, oh and no grands yet. He will get married to his 2nd wife next year, so hopefully grands before we are too old to enjoy them.
