In all seriousness I wonder if he has had a minor stroke or is starting to get signs of Alzheimer's or something along those lines. Not like full on but the very beginning. He is doing things kind of like my dad did when he had a minor stroke. Misspeaking, mixing up words, losing track of conversation, etc. Over time it got better but he has never been 100% since. And it's been 10 years now. I really wonder if boler had something similar. Sure hope not.
