Sorry to say that Happy - but "yes" I would be laughing in this situation...
Otherwise when I see somebody falling - depends on circumstances, who's that person (elderly/young), if that person is injured etc... - first is better to check up if everything's OK and provide help and then eventually laugh together... (after the CPR)
Apparently your daughter got a guts and she handled that very well - high points for her
And I believe you must be very proud of her achievements
