Yesterday, Shanthi was explaining the thodatha manaivi situation to RK, and I was wondering about all the young children who may be watching this show in the evening, maybe while they are eating their dinner. Is all this really necessary? And it doesn't explain the scene shown ages back when Shanti expressed regret to Karthik that she couldn't have another child after she had to have the hysterectomy. If they never touched each other, where was the need for regret?
