What does silence mean?

I call but you do not respond Maybe you did not hear Or are you ignoring me?

You ask a question but I do not reply Because I do not know the answer Or I do not want to talk

Silence can end an argument Or it can start one Silence can be used as denial Or as acceptance

Silence can help you gather thoughts Or mean you dwell on them Silence can be enforced Or it can be a choice

Silence can bring you peace Or it can be disturbing Silence can be golden Or it can be stony
