My dad (81 years old) does not get around very well. He is more than willing to let my mom (76 years old) cater to his every need, including helping him with transfers. Frustrating! My daughter graduates from high school in June 2018. They are planning on coming to the graduation. He should not be traveling because the risk is too high. It just isn't safe for him to travel from OH to CA. Problem is that they are in denial about their present situation. How do I convince them it's not a good idea without hurting their feelings? My mom could easily make the trip and we would love her to but then that leaves my dad in the cold. My siblings live in their town so he'd have people who could look after him if Mom came solo. I'm stuck between a rock and a hard place. What do I do?? I should mention that in addition to the aforementioned, my dad is NOT pleasant to have around. We wouldn't miss him which makes me sound HORRIBLE. I don't want my daughter's big day to be ruined but I also don't want to hurt his feelings. Any advice?
