> A stupid man > and an undisciplined one > laughs at everything. > He hasn't learned > a lesson that would do him good: > he himself isn't flawless. - People who are not aware of their own shortcomings tend to mock others - similar to the biblical "let he who is without sin cast the first stone" - people shouldn't mock others as often what they are mocking is something they themselves are guilty of - people are not flawless and we all have our short comings - and a wise lesson about this is to be patient, tolerant, and respectful. - Could also be said that the things you pick out and laugh at in others - are qualities you yourself are short in - mocking your own shortcomings present in others
