At the park yesterday with my DD and her friend . I'll call DD's friend Z. (both girls are almost 8 years old).
In the park there's a musical chime set which is set up for one DC at a time.
Z started playing with the chime and a younger child (around 5 or 6) came up to ask for a turn.
Z said outright no. The little girl said she would really like a go.
I explained to Z that the little girl could have a turn after her. Z said no she was playing with it and walked off with the chime.
I explained to Z that she could have it for 5 minutes and then to give the other child a go . NO!
The other child kept asking her mum how long until her turn - mum counted down to 3 minutes , 1 minute etc .
After 5 minutes I went to Z and asked her to pass the chime to the little girl.
She ran off with the chime and refused to give it ; she also became increasingly annoyed with me !
I was at a loss of what to do as Z is not my child and I couldn't physically remove it from her . I did tell her we were leaving but by this point , the other mum had tutted and walked away 
Z was now in a bad mood .
I'm now doubting whether I should have forced the issue . It's public property and I think by 8 Z should be able to take turns 
WIBU?
