Recently, I attended a birthday party for a friend. Other guests knew I was a ghosthunter and it was no big deal. One of the other guest's daughter's was a bright 12-year old who asked me (when I was talking about a location) if there were ghosts there. Without missing a beat I said, "Yes. There were." She just said "Wow" and her mother's face blanched slightly. And that was that. I wondered for a minute afterwards if I should've thought about it before telling her that, but I think that the girl appreciated my being truthful with her. What was I going to do? Lie? I didn't want to do that.
Years ago I did a lecture on haunted D.C. and ghosts and a co-worker brought her 10-year old son, who told me afterwards how much he enjoyed it. I really enjoyed hearing that. A lot of times, kids are the main ones having interactions with ghosts and their genuine feelings and concerns are dismissed or disregarded by the adults in their lives. Kids and teens like to know that they aren't seeing things too, much in the same way that adults do. I've had so many parents express to me the experiences their children have had and sometimes they--like their kids--need that reassurance too. That whole "You/they are not crazy" thing.
I know parents want to shield and protect their kids. That's absolutely understandable. I would too. Sometimes, though, they can take more than you think they can.
