Because there seems to be different rules for celebrities. And Serbia won’t do anything to Djokovic, no matter what he does, whether it’s COVID measures or something totally unrelated.
And where did you get the information that kids are less likely to get sick? Why then were schools shut down and masks necessary when finally opened? What’s the point of vaccines, quarantine measures, distancing, masks, PCR tests if the rules won’t apply to everyone? When I arrived home last in March 2020, when measures were first introduced, I had to stay at home for 4 weeks, and the authorities would call my home every day for those 4 weeks to check on my whereabouts. I didn’t agree with those measures, not do I agree with a lot of the measures being practiced now, but I still have to follow them otherwise I would need to pay a relatively hefty fine.
I blame the Djokovic camp and the Australian government for making a meal out of this.
