Best friend has never cut the nails on his right hand because he says it’s not possible? He has always persuaded either partners or friends to do it for him. He has health conditions or impairments that mean he actually can’t do it. I live nearby and he wants me to do it for him. He’s a grown adult in his 50s. AIBU to refuse on the grounds of he really needs to sort this out and not rely on people to do it.
