My youngest son lives in Abu Dhabi at the moment. In the last 12 years he's been overseas, he's lived in Ho Chi Minh City, Beijing, Dandong, Sien Riep, Phnom Penh, Belgrade and now Abu Dhabi. Yes he's a tour operator. It's difficult to videochat because of the time differences and his work schedule but we keep in touch through texts on Messenger. My eldest daughter lived overseas for 12 years and we skyped about once a month for 2 or 3 hours! I've always left it up to them to schedule time to chat that suits them.
