My Dad travels a lot for work, it has been this way my entire life. The last 7 years he has been on a schedule where he works 30 days and then has 30 days off. Growing up, my Mom had me, my sisters, all of our activities, and work to keep busy. Now that she retired she has found new hobbies. They talk on the phone every night and email each other or text each other during the day. She said it never gets easy to watch him leave, but the reunion when he gets home is always wonderful.
