Question

Vidya is a married woman who has a cleft chin (a deep hallow in her chin). Vidya

has recently been blessed with a baby girl who has also a cleft chin. Anitha is a

close friend of Vidya. When she learned that Vidya’s baby girl also has a cleft

chin like Vidya, she got worried. This is because Anitha has a huge scar on her

left cheek which remained permanently after she got a cut on the cheek during

an accident which took place in school days. Anitha is worried that her baby

(which is due shortly), may also have a scar on her left cheek just like her. One

day, Anitha’s niece Radha, who is a science student of class 10, came to see her.

Anitha shared her apprehension with Radha. Radha could understand her

problem. She told Anitha that her case is entirely different from that of Vidya.

Radha explained everything to Anitha clearly. Anitha was now very much

relaxed.
