30k people, so a medium town size. 15 to 20 minute walk from school on the last day of year 6. About 6 of them. Dh would be on call as I would be over an hour away. Group of boys and girls. Its dd first time without an adult, although she knows town well and how to get home. (30 minute walk but will probably phone dh
)
Yabu let them go
Yanbu they need an adult
