Every year there are at least three milestones in my life related to my children: birthdays, beginning of another school year and Christmas time. Each one of them is bitter-sweet, bringing tears to my eyes when nobody’s looking, and filling my heart with so deep feelings and huge desires that leave little space for my lungs. This is one of those days. It doesn’t get any easier: I don’t get any tougher, any more skilled to not feel like I am falling apart a little, or a lot, trying to hide it behind a timid smile and a wave goodbye.
