Q. Why did Sulekha start stammering?

(सुलेखा ने हकलाना क्यों आरंभ कर दिया?)
Answer: Sulekha could not speak till she was five. When at last she learnt to speak she started stammering because other children often made fun of her and mimicked her.

(सुलेखा पाँच वर्ष की आयु तक बोल नहीं सकती थी। आखिर जब उसने बोलना सीखा तो उसने हकलाना शुरू कर दिया क्योंकि अन्य सभी बच्चे उसका मजाक उड़ाते थे और उसकी नकल उतारते थे।) ।
