If you have ever dated an eldest daughter, you have probably noticed one thing very quickly, she always shows or have control over everything. she checks if everyone got home safely, ate well, remember birthdays and always notice if something is wrong even before anyone says a word. They always love to check on people and it comes out so naturally because that's what they are doing for years.
Most of the eldest daughters grow up feeling responsible for their families and loved ones. They help their siblings, support their parents and grow up mature. That can make them a good partner, but it also means that they are carrying something much on their shoulders.
