My sister has Type 1. She has asked our other sister and me to do a DAFNE course. Our other sister lives in the same small town as her, sees her regularly, and has agreed. I live 150 miles away, and usually only see her as part of a family get together. I don't see the point in doing a DAFNE course. My sister is upset that I am being unsupportive.
I know this isn't AIBU, but - am I being unreasonable to refuse? What would a geographically distant relative gain from doing a DAFNE course?
Is there anything else I could do to show that I'm supportive, without having to use up some of my holidays to go on a DAFNE course?
