OK she did receive a text from the volleyball coach. That text was received if I remember right at around 8:45 is what it said and it was about the schedule for the tournament. So lets forget about the v-ball coach because I know for a fact there is nothing there.
She sat there and texted throughout the entire movie and when she made the call it was towards the end of the movie. She told me that she had to go to the bathroom but I have never seen a woman go to the bathroom so quickly. Plus the bathrooms were quite far from our theater. If she was going to call our daughter then why didn't she just say that?
