Yesterday, I had several hours hanging out one on one with Eli. He showed me how to cast/project a phone onto the Roku (using a mirroring app.)
We then watched videos from his phone on the television via the Roku.
Also, we watched “Free Willy” and later went to the park. We had a picnic there, then he played with his drone and kick ball for a bit.
He was superbly behaved overall, and the time was very pleasant.
