Most people have fairly normal relationships with their parents, but there are still some people out there who sympathize a bit too much with the 13-year-old from "Game of Thrones" who gets milk straight from the source.
I can't say I personally know a lot of people whose mothers decided breastfeeding was just too much fun to ever stop, but I have encountered more than a few people with parents who seemingly did whatever they could to ensure their child was emotionally stunted.
One of the most universally recognizable examples of this phenomenon is probably Justin Bieber, who has a done a great job earning the "emotionally stunted" label thanks to literally everything he does.
I'm not going to attempt to psychoanalyze him to explain his behavior, but I feel like having the kind of dad who thinks it's a good idea to let the whole world know he's proud of your penis probably didn't help much.
However, the Biebers are far from the only family that seems to have a little bit of trouble establishing boundaries.
I guess some people might consider this normal, but those people probably aren't.
