She's 17 and in 6th form, currently under performing in two subjects. I can see from the itemised bill that she is texting constantly throughout the day. Yesterday I raised it with her, said she would be better stopping this and she could talk to her Friends anytime. She said 'Yeah, I know'. I shall be monitoring this but as she's 17 I think she knows what she has to do herself and should take responsibility, I've said it's up to her if she uses it but the time is best spent listening to the teachers. Anyone any ideas with this? Short of removing the phone of course!
