A burden? I don't think so...there is nothing THEY can do.

a) "nothing" represents a suggestion by others; which ones consent upholds as a burden within "everything" perceivable.

b) suggested pluralism (they) tempts perceiving singularity (one) to burden self with the suggestions by others.

c) being able to perceive implies being at the center of an impressing surrounding (perceivable)...suggested "I don't think" tempts one to ignore that.

Reacting (perceiving) to impressing (perceivable) implies expressing (comprehension)...while burdening self with suggestions by others represents self repression, while giving others ones consent to depress with suggested.
