Family Troubles

Why is it that everything to do with my family has strings attached. I will try and make this a brief as possible but I need to give you some background first. My father passed away recently after a long protracted fight with cancer, I hadn't been down to see him or mum in several years, so I made the effort. I hired a rental car and drove the 3500kms to see my parents. The whole time I had not seen them they made out the me that they had no money that their cars were falling apart and that they needed help. I arrive in the driveway to find not 1 but 2 new cars one only months old. I didn't get upset or anything just let it go because dad was failing. I stayed a two weeks then returned home with a promise I would be back at Christmas, another 3500kms and I was home. Week before Christmas in my brand new Suzuki swift, I drove down to see them again. We had a wonderful Christmas, the first time we had all been together in many many years....
