Was it messed up for my case manager to laugh about her son passing out on a roller coaster?

I was meeting with my case manager earlier. We often talk about what we did over the weekend. She started laughing uncontrollably, and said that her, and her son whent to six flags. They went on a roller coaster, and he passed out briefly near the end of the ride. I was sort of laughing because I thought it was a commen thing that most people found funny. I didn't really find it funny, but I laugh when I'm uncomfortable. She said "I'm a mean mother". I was just like "well... I don't know".
