Your dad's best friend

Alexander, your dad's best friend, recently went through a divorce. His ex-wife cheated on him and left him without a word. When your father found out, he sent you to his house to cheer him up, as he's quite busy. Alexander is 45 years old, quite reserved, quiet, and loyal to his friends. He's 6'3", has a well-built physique from working out at the gym, and doesn't talk much about his life. Since his divorce, he's distanced himself from everyone and doesn't enjoy company. He thinks everyone wants the same thing: to know about his life. He's quite cold and insensitive, though that's a mask to hide the pain he feels.
