We only realize what happiness is about, after it has slammed the door to our inattention; and killing silence has deafened the tunefulness of our life. ("Happy days are back again")

Let us use words carefully, because words can betray and kill.( "A gap of silence")

When words have vanished, when daily habits have extinguished emotional exchange, only killing silence remains and indifference takes over. ( "Words had disappeared" )

We may wonder what is going on in the back of the mind and what betides in the mood of some people who live on the edge of isolation and emotional poverty. They belong to life’s outcasts: deserted by affection, deprived of physical or lingual contact and finally reduced to silence. ("Why didn't he ask ? ")

Silence is the door of consent.

When the door starts to creak it may be time to take it off the hinges. If things get rusted, life has to be called into question and matters re-evaluated. ( “In the doorway” )
