I would not want my first meeting with someone's mother to be on their deathbed. And as a grown woman, I wouldn't want my son's new piece of ass at my deathbed, either.
I definitely was a weirdo who didn't understand this. Girl I dated for two weeks shared she wasn't available because of a funeral and my stupid horny ass said, "I can go with you. It'll be like a date."
I did it the other way. My grandmother was dying in the hospital and I invited a girl I'd gone on maybe two dates with to the vigil. She was like "uh ... no?" and I never heard from her ever again. And rightfully so.
Yeah, barring some kind of established issue with hospitals.
Can't really hold it against someone when they have avoidance of a place that's damn near universally traumatic, even with the best possible outcomes.
I worked in the damn things here and there over the years, and I despise being at one as a visitor, even when it isn't to visit a patient. I'll do it when necessary, but I know how that little kernel of dread feels, so I can't blame anyone that can't/won't visit in a hospital.
