The Brightest Colour

I was once my mother's favourite colour Her bossom was mine and mine alone Under her wings l would hide when it was raining Then a stranger tiny but loud arrived He took my place and took one of my mother's eyes My heart was bitter but his smile l could not resist Over the years l have come to accept He is my mother's second colour But the only question is Which is the brightest of the two? Brother is a brother created to be loved by you and me even though they take our space and some of the benefits we had
