PHILADELPHIA (CBS) – It’s not unusual to see somebody over-sharing on Facebook, but one expert says more-frequently the guilty parties aren’t kids or young adults, it’s their parents.

Sharing is the basis of social media, but more and more people are sharing a little too much information.

But Annie Heckenberger, a VP at the ad agency Red Tettemer, says so-called “TMI” offenders are not who you think they are.

“It’s including people who are in their 40′s and 50′s who are more seasoned, but I guess that’s evidence of the fact social media is a completely new landscape and everybody is learning along the way,” Heckenberger explains.

Heckenberger advises there are some key things you should keep to yourself.

“I would start with anything proprietary that you are working on. I would really think twice and three times, maybe four times, about posting anything related to work, anything related to breakups and really just any interpersonal arguments,” Heckenberger says.

Over-sharing isn’t just a potential source of embarrassment, social media posts are the subject of legal searches when you get involved in a lawsuit.
