That outside classroom looks amazing. Our primary school has a fair bit of outside space and in the summer the teachers take the classes outside for games or reading. Our school is doing a bicycle/scooter ride on Friday. It's a great idea to get them out of the classroom for a while if possible.
Yes, Sionnach, that will be a polite 'no' to the invite. I don't know the family either, so it doesn't help. There could be five, fifteen or twenty-five children invited for all I know. My DD is a bit put out about it as she knows that another pal of hers in the park is going. That's typical about the people complaining about the pods in school organising sleepovers!
The rising numbers are worrying. I hope people will use their cop on and follow the advice.
