The children are still in school. There is a VERY tight turnaround between getting them up and them needing to leave for school so nothing which disrupts the routine too much. Nothing which raises their hopes that school is cancelled. Nothing which will embarrass them too much (teens/ preteens). Previous jokes have included telling them they had to go back to school a day early to make up for snow days. Getting friends to text and changing name to their school that they had to wear school uniform in lockdown. That sort of thing. If I can catch them while half awake even better. One has set an alarm in the hope of not getting caught out again. Any ideas gratefully received!
