Fighting between siblings is normal at a younger age, to some it continues up to teenage years or even at early adulthood. But as we mature, we learn to value appreciating having siblings, that we can share things and life with. It is normal to once in a while have an argument or misunderstandings with them but when life is difficult to face and we are in the edge of uncertainty, that is the time that we realize that the only person that we can lean on to is our closest relative and that is our family, including our siblings. I have experienced that a lot of times. We fought, we argued, had misunderstandings but in crisis, we help each other to get back on our feet and rely on each other's strength.
