If I had to guess I would suspect a majority are not fully compliant
I'll start. Ds (16) fully compliant, but he is happily an introvert. Dd (18 next week) started well with socially distanced meet ups but has infringed the rules to stay over at a friend's, and has also acquired a new boyfriend which certainly hasn't respected social distancing. She hasn't attended any parties or mass gatherings though. I feel a niggling sense of guilt (but perhaps not as much as I should)
