I know it was morally right and ethically correct to confront him, but now he is giving me the silent treatment and I'm wondering if I was wrong to confront him because I know he has dementia? Other things that were obviously "taken" have appeared in his yard, such as some historic bricks from a nearby renovation project & some wild flowers from a nearby public park. My husband told him the bricks were being re-used at the reno site, so my dad did return the bricks for a week or two, but I noticed they re-appeared in his yard. Today I thought it would be fun to take him to a farm stand to buy some fresh produce. Before entering the farm stand, he walked right into an adjacent orchard and touched a bunch of beautiful red apples. Inside the farm stand, he noticed none of the apples were available for sale, and I explained that the apples weren't ripe yet and that the farmer would know when they were ready to be sold. He said they looked ripe to him and walked back into the orchard, picked an apple right in front of the farmer's house, and put it in his pocket. When he got in the car I asked if he had taken an apple and he said "well, yes". I said he shouldn't do that, that I knew the farmer (which I do) and that I was not happy that he had taken the apple. He proceeded to argue with me that the apples were ripe, that the farmer wouldn't miss it, etc. When we arrived back at my home, he soon pulled the apple out of his pocket and began to rave about what an intense bright red color it was. I asked him not to bring the apple out into my house, that I was upset that he had taken something. I asked him if he would take an apple from a store without paying, which really offended him because he said of course not, that at his ripe old age I should know by now that he is not a thief. I then went on to point out that he would be (and has been) very upset if/when neighbors wander into his yard to help themselves to his grapes (he has a few vintage grape vines in his yard). He then went on to say he was "sick of being treated this way" and then stormed out of my house, leaving without having our usual brunch. The storming out of the house part is nothing new, I've endured walk outs and hang ups since childhood. The "help yourself" attitude isn't new either- over the years he's been confronted about minor infringements such as using garbage dumpsters that aren't his, etc. I've always had a rocky relationship with him. My husband and I and our children are literally the only people left in his life. He still "lives alone with help mostly from me" about 30 minutes away in a rental home that my husband and I own. He is still driving, though he's been restricted to local familiar routes by his doctors. My main question is should I stop confronting him about these petty thefts, because my long term goal is to keep him safe and cared for and to have his trust for when I really need to bring in more outside help or move him into assisted living? I guess in writing this post, I realize the question is even bigger. How will I know when his belligerence is just his baseline personality, or a sign that he really needs more help than I can provide on my own?
