If every vaxxed person behaves responsibly, then opening up might be possible. Unfortunately from observations so far, not many people are like that. See those with masks on chin, no mask and smoking, chatting in groups at close quarters without mask, etc.......

You are very observant, there are indeed right to say that no mask and smoking, chattering in groups at close quarters without mask.  Our govt. will like to see all wearing masks and also all being vaccinated.
