I was dropping ds and friend's dd to infants this morning and as I walked through the gate to the playground realised that the loud and hectoring voice I could hear was coming from a parent walking about 10 feet behind me having conversation on her mobile. Between coming through the gate and reaching the classroom she swore five times at least ('he's fucking useless', 'I'm not fucking having him break his promises to her! Etc) in such a loud voice that both the children with me turned and looked at me in alarm and asked why she was swearing. Was I unreasonable to phone the head when I got home and ask her to say something to this mum? Or should I have quietly said something myself (and risk getting slapped - she's much younger and tougher than me
.
On a slightly separate note - feel sad for her kids that their mum is having angry public conversations about their dad (several other things she said point to this being what she was probably talking about).
