I think that's always a welcome change in the school day. One might also discover unexpected talents in oneself or one's friends that normally lie dormant... I'm glad you were able to enjoy the day.
The smog gives me a bit of grief... Is anything being done about it?
Several smog hotspots are under 'green lockdown'. Some brick kilns, plastic melting factories and other toxic emission sources are being demolished. But it's the burning of crop waste that has a big hand in smog. I haven't heard anything being done in that regard.
