My dd10 has been friends with a girls for a long time. Last week I received a text in the morning from her mum saying my dd was showing ‘threatening behaviour’ and was going to ‘spread nasty rumours’ about her friend and I should sort this out with my daughter. I asked my daughter and she denied it, and was a bit shocked her friend had said this about her. They went into school that day and played happily together and everything was fine. Even the friend’s mum acknowledged that they were both fine at school. AIBU to be annoyed at the mum for accusing my daughter automatically and not finding it strange that one minute she finds my daughter threatening and the next she’s best friends again? Luckily my daughter isn’t sensitive and has bigger things going on in her world that this doesn’t bother her. But it bothers me that my dd was accused of something (no witnesses or evidence) and the mum has just moved on, without even acknowledging her dd may have made this up?
