People Go To Religious Places But Do Not Learn

It hearts me very much when I see,people go to religious places like-temples,churchs,mosques,get together of religious people to meditate or worship,prayers,sing religious songs regularly without fail on time ,but the moment they comeback they start accusing/commenting or complaining about each other talk like other general worldly people,start cunning ness,be deceitful,retain proud rather than becoming simple truthful person and adopting simplicity.I say, why to go to these holy places if they can not learn something or they cannot change their attitude? Merely putting our attendances regulary at the above places shall not promote us,unless we change our attitude/behavior/thinking.It is just like we go to school put present in attendance book,attend classes also, but do not learn anything and fail in exams everytime .
