My Ds's year group WhatsApp (primary) is brilliant fun. So much fawning over one or two top dog /queen bee mums, passive-aggressive comments on who has taken little Phoebe's brand new trainers or whether to have a collective or individual teacher's gifts. I also find the herd/mob mentality fascinating and a bit scary in equal measure. What are the weirdest /craziest posts you have witnesses on WhatsApp groups?
