No need to apologize :) The glass (this was the previous story) was a bit of freak luck. Which I even acknowledged — I think that’s called hanging lampshades.
What happened was a woman tripped and fell face forward while carrying a big terrarium. One (of the many) shards of glass that cut her, got stuck just above the heart. What Maria did was push it in deeper by gently increasing the pressure on the shard with her foot.
