To Friend or Not To Friend

We all love our parents and turn to them when we’re in need, but would you like them to hear the conversations you have with your friends on the school playground or lunch queue? Social networking sites have become extensions of the school hallways, so would you add your parents as “friends” and allow them to view your online activities and conversations with friends?

In the past the generation gap included a technology gap, where children were up to date with latest technology and parents were left behind, content to continue their day to day lives as they always had because they had no need to know more about technology. However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation to education themselves about social networking sites.

These days many people are attracted to social networking sites because they can choose who they have around them; there’s also a certain amount of control over privacy that we don’t get in real life. Sometimes we feel that privacy is violated when we must accept a “friend” request from a parent or family member.

It’s a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand we don’t want to “reject” their request because that might hurt their feelings or make them feel you have something to hide. On the other hand if you do accept, then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before.

A recent survey suggested that parents shouldn’t take it personally if their child ignores their request, “When a teen ignores a parent’s friend request, it doesn’t necessarily mean that they are hiding something, but it could mean that this is one part of their life where they want to be independent.”

Perhaps talking with parents and giving explanations would help soften the blow if you do choose not to add them to your friends list.
