Ever feel like your parents don't understand you at all? I know it sounds horribly stereotypical but you can't deny feeling misunderstood. This is common and it isn't just our teen-angst making us feel like a NOFX song. Parents really just don't understand us; it is as simple as that.
This lapse of understanding is mainly due to the rather large generation gap between us and our parents. Times have changed, and for some reason, they have a hard time understanding this at times. Back when they were growing up, things that we find socially acceptable were considered horribly inappropriate. For example, guys and girls just hanging out is a lot more common than in the 60's and 70's. And don't even get me started on conduct at dances. Back then a guy politely asked a girl if she would like to dance. Now they just come up behind a girl, grab her and sweep her to the floor, and all this while the girl's wondering, "Do I know him? Is he attractive or what?" In the older days, girls wouldn't have to wildly signal to their friends to help them out of a dance.
So considering we are a much more desensitized and open generation, it is only fair that people who grew up before us may have a hard time comprehending our actions. And, while I'm not trying to completely justify their intolerance, we do have to understand that it's just new to them. Try explaining what you are doing and remind them that times have changed; in the nicest way possible of course.
