Is the cell phone changing our views about polite and impolite behavior? for example, is it polite for someone to be talking on their cell phone while ordering a drink at starbucks?

a cell phone is changing our views in both polite and unpolite ways because these days I see people at dinner tables on their phones taxting and not actually socializing with the people around them but at the same time people who like other people posts on instagram and wright good comments are being very polite to the person who posts it.

yes, cellphones are changing our views about impolite and polite behavior and yes, it is impolite for the question.

answer; i believe the correct answer is (expression); good luck
