It isn't mythical. I am just surrounded by closed office buildings. My own building is the only building converted to apartments and so I can only see offices around me and it doesn't have balconies.
No one claps near me . I can't hear a sound.
My apartment is in a converted office block. Every building around me is an office block so they are all closed so nothing. If I didn't see it on the telly I wouldn't even know it was happening
