Ever since I was a child, and that I'm an adult now, I've never ceased to wonder about the relationship of a mother with her children. As far as I remember, I can tell that I skipped no day to look at my mother's face. This has been happening for so long and, despite the accumulation of years, my mother looks prettier ever day. I cannot explicate nor understand how my eyes work. Is this maths? Chemistry? Physics? Metaphysics? Tell me: Do you feel the same? Is this how our brains operate that they control our sight and feelings?
