What do you think about me letting my grandpa with Alzheimers go to the theme park alone?
That is terrible! How could you let him go alone?
He is a lucid man. It would be a waste to not visit the theme park before it closes.
If you are in charge of a family member, you need to make sure to take care of them properly. Letting your grandpa go alone was irresponsible of you. Take better care of them or let someone else do it next time.
Don't talk to my grandpa like that. It's just a game and it's no big deal.
Knowing that a family member has alzheimers should make you more motivated to look out for and protect that person. Letting your grandfather go to a theme park alone, with this condition, is the wrong thing to do.
