Mother & her two sons

I came to the eldest one and asked" how old are you?" " I dont know", he replied innocently. Then I asked " Do you go to school, little bro? He smiled and said: " go to the sea is better and getting more fun than going to school. I could help my mom to collect sells, also could play with my younger brother"... I swallowed my tears and it tasted bitter, salter than sea water. Just wish them all the best!
