f it brings up a lot of shame for people...shame worth listening to. If you can do that, there may be a chance he will come around (at least to the idea - even if he may not go himself).

Also worth noting that its not up to you to convince him. You're doing good work by figuring out what you need and getting yourself help. Its not your responsibility to prove to everyone (even close family members) why you need what you need, and/or why its helpful to you.

Do you think climbing grades will reach a maximum difficulty? IE. Is V16 the hardest boulder that will ever be climbed? How about sport climbing, is there still much room for harder sport climbs into the grades of 5.15+ or 5.16-?
