DD(11) and DSD(12) have a bit of a rocky relationship. Best friends one minute, can't stand each other the next (literally). DSD invited school friend (different school to DD) over a couple of weeks ago and fireworks ensued including some very mean texts/phone calls from friend & DSD to my DD. All dealt with and my DD has no contact with DSD friend. Anyway, today DSD is with school friend for tea, my DD is at an activity and the DSD has tried to call numerous times. Im, understandably a bit anxious about whats likely to be said between them as this friend appears to have quite an influence over DSD. Should I warn my DD that DSD is with her friend when she phones back or should I just keep an ear out and support DD if needed. Can you tell Im expecting it to be explosive?
