See this is interesting. I remember reading during my freshman psyc. class that there are certain moments or events that can be seriously detrimental to the relationship between a mother and her daughter. If I'm not mistaken, this was one of them. Something about chemicals in the soap causing a reaction in the brain something or other.
I might just be making this up. Sometimes I lie. But anyway, I'm glad that you and your mom didn't experience this.
But about the movie, I really have always liked it.
