One of my "friends" at work has begun to have grand mal seizures randomly throughout the week.
She is a lovely twenty six year old mother (of a five year old boy) who has never been diagnosed with such difficulties, until a month ago. She still does not have a her medication stabilized.
Today, she had one right in front of me.
She looked up and made this "bird sound" and I grabbed her and helped her to the floor gently, while she became very stiff and vibrated.
Fortunately, she does not FLAIL her arms and legs like my brother-in-law used to when he broke his collar bone and his wrist beating his chest and head.
