Since we inherit our temperament from both/either parent, I would imagine that the split of emotion and sensitivity would be fairly even.
However, I HAVE heard often and often: "If mama is happy, everyone is happy. If mama isn't happy, then no one else is either." I don't know if that's true or not, especially in these days of husbandless and fatherless families.
Haha, yes, I believe you are correct on all points!!
