The death of one's child might make a person distraught, exhausted, irrational, impulsive, frightened. Maybe that's why she practiced calling 911?
True...but, and I know I might sound like a jerk here, do you really need to practice dialing three numbers???? It sounds like either she really had a legitimate reason for calling, and then either changed her mind or was coerced to hang up...or she was under the influence. I pray to God that I will never be in the position to understand her pain firsthand, but I really don't think (even under her circumstances of fear/pain), that there is a legitimate reason to "practice" dialing 9-1-1.
