Taking shrooms with my elderly dad

My dad is a healthy 80. He did his fair share of tripping in his youth, but it's been a while. He'll take a THC edible occasionally. He has treatment resistant depression and has tried a dozen pharmaceuticals but they generally don't work or make him agitated. I also have depression and shrooms have really helped me a lot so I want him to try them out.

I'm visiting him this weekend and plan to make a mid-strength tea for us to have together. What are some activities I have have planned in case we don't find a natural progression? He lives in a house in the suburbs with a big yard and a dog, has tons of musical instruments, has periods of being into making art, likes writing. My current idea is to bring materials to make mobiles, and also other random art supplies.

Thoughts? Advice on doing shrooms with an elderly person? On doing them with a parent?
