Laughter is an extrovert expression of the deepest joy and deepest sorrow.
Tears are an introvert expression of the same two.
Silence is one step beyond, into the realm of profound impact. It does not necessarily mean there is a lack of response or lack of understanding, but that your response is more intense and it cannot possibly be displayed… at least not yet.
Some things just cannot be expressed without undue complexity. And a good part of it is letting time process it, unravel the details like a tangled skein.
Complex reactions need to ripen like grapes on a vine.
So, take your time, as you would with fine wine, and never underestimate silence.
