My father is 64. My mother passed away 4 years ago. My father still works. He's self-employed a male dominated industry. He doesn't have any friends and hasn't since university. He's very introverted as well (so was my mom). He has no hobbies -- spent all his time working when we were kids.

His brother and sister lives far away and so do I. My sister lives close by and does what she can but she has a very demanding job. He doesn't have enough money to retire or take a vacation and wouldn't have anyone else to run his business. He has a golden retriever but he's that's pretty much it.
