Calls Save His Days

My brother in-law works overseas. He has been out of the country for almost two years now. He stays in touch thru chats and calls using calling cards. He says it is tough being away from his family just to earn a living. He misses his kids a lot. Thank good ness for easy access to technology these days that he is able to stay connected with his family.
He plans to come home next year. But still contemplating if he will still work there again. He says it takes hoards of will power to stay focused because of homesickness. Thus he invests on calling cards
