I almost understand woobies, up until the age of 5 or so, after that, it's clearly an aberration.
I have a number of adult (usually female) patients that arrive with what the biz is called a "comfort object." They are more colloquially known as diagnostic criteria for Borderline Personality Disorder. (seriously, only the borderlines bring the things).
I do not know what to say about Mr. Hairbrush, especially given that it's more like the
wire monkey, but without the food source.
Does Dadfobble use any hair care products with particularly distinctive scents? Maybe that's the attraction.
