Hey Luke,
thanks for sharing something so personal. I'm glad you enjoyed it. It can be very odd to be back with your eyes open. Very strange comments indeed! Makes we worry about what my children would be getting used to as normal, if they were still there.
I gave a sit down first talk with my sister, when I was 5. Mainly due to nerves, and the stool wasn't big enough yet. I still remember my first talk on my own. Jonah and the big fish. It might as well have been "the Care Bear Stare, and what it can do for you!".
I hope and it sounds like you still have visitation? Does he get to be with you often? If so, you just keep doing what you are doing. Showing support, and not letting them be the only ones giving him community.
