Why

Sona and Mona, the sisters, always up to some mischief.

Sona: "Didi, I hate to go out in the sun".

Mona: "Why?" there was surprise in her voice.

Sona: "Because it'll make a difference to my skin tone".

Mona: "Why?"

Sona: "I have such a beautiful skin, I don't want to … "

Mona: "Why?" She interrupted before her little sister could move along with her babble.

Sona: "Didi, I want to look beautiful".

Mona: "Why?"

Mona carried on with her mono syllabic reply. Sona was getting irritated. She jumped up from her chair and lunged forward. Before she could get hold of her, Mona ran out of the door into the garden to save herself from getting hurt from the wild attack of her little sister.
