I genuinely don't know what advice to give my DD about one particular friendship.My DD is fine and happy at secondary school.However she is being hurt by her favourite friend from primary school, who I'll call 'A'. My DD and 'A' are now at different secondary schools but still live around the corner from each other.Whenever my DD goes to see 'A' another girl 'B' calls around too.My DD sees 'A' as her best friend and would like to hang out with 'A' on her own sometimes.I know it seems pathetic of me but this problem has been going on for over a year and DD is hurt and I don't know what to advise.I have frequently suggested that DD talks to 'A' about it but she says she can't .......Any advice from you experienced parents out there?!
