Boredom is probably more frequent and more tormenting if you do not have sight or hands.

Some people do not mind losing the person or thing that some people would kill to have.

Not everyone who talks less or keeps quiet whenever they are with or around you does that because they find you interesting or knowledgeable; some people do that because they find you boring or ignorant.

People and things need not be interesting to us for them to be beneficial to us.
