Sometimes...
...I think I'm one of the few people that believe that teenagers shouldn't be coddled, and I'm sure I'm going to get called a little cold for saying that.
I guess I just see teenagers enter the real world and not being very prepared since mommy and daddy treated them as the Perfect And Only Snowflake In The World. Yeah, there're some dangerous things and people in the world. It's called, well, Life. You interact with soceity and you take that chance every day.
The world can be an amazing place but it can also be ugly. When I have kids, I want them to be prepared and while I will love them with all my heart, they will need to fail and learn from their mistakes. No lies, no wool over the eyes.
This isn't really directed at anyone I know in particular, but I'll read news stories or FB/LJ posts. Perhaps some people do this on purpose to keep kids in line with their beliefs and values, or because they have a hard time accepting the face that their child grows up someday.
