Two pieces of advice here.
1) If you are going anywhere down there, please take a GPS and a PLB. By all accounts it is very easy to get turned around and lose any sense of direction.
2) Always remember that you both have someone very close to you in common. And if it was not for your father in law raising his son to be who he is, you would not have the Sideshow that you have now. Please try to look at this as a chance to get to know him and turn things around. I remember the impact on my mum when my dad was fighting before he passed and it took a lot from her. I suspect he is dealing with similar issues. After 3 years I still miss my dad every day so I can only imagine how mum feels. Use this chance to build something between you. Whether he says something or not, he is going to need both of you to support him through this very soon, if he does not already.
