Dd11 has had the same best friend for approx 5 years. They get on well and it mostly works. But over the years shes had some nasty comments from her BF and I've had to put it down to age and leave them be as I would rather not get involved.
Recently though some of the comments have been worse for example, asking if the bad smell was DD. Asking to see birthday presents she received then saying she is bragging. Asking if she has a certain toy (yes) then saying how she doesnt like said toy but suddenly buying the same toy. I heard her asking DD one day if her mum eats pizza to which DD replied saying yes of course! Her reply was that her mum doesnt eat pizza as she likes to stay healthy.
Its very competitive, is this just normal for this age?
If this was a boyfriend we would be running for the hills but is it just kids being kids?
