To re-phrase this slightly, how many lives are you happy to sacrifice for your life? If just one person has to die so that you can have a piss up is that okay? This is purposefully inflamatory, but this virus can't be considered at an individual basis, that's not how it works. It thrives on our sociability.
Through no fault of their own, some individuals have had their lives shortened by this virus. Not only that, their families haven't been able to grieve with limited funeral allowances. Imagine that - someone you love is dieing, but you cant see them - not only that, but then you can't even get together and have the support of friends and family after they have died. Imagine you're one of these people then imagine seeing someone decide they're "done with lockdown" becasue they've had to sit at home and work.
Healthcare, care workers, teachers, supermarket staff, delivery drivers all have had to work throughout this pandemic. These people have been purposely putting themselves at risk for us in the general population so that we can have the privilege of being able to shield away from this virus.
You are allowed to make your own decisions and everyone has their own position that they are coming from. Just try to understand all contexts. Please.
