Dear I don't know why you are so upset that you are blaming Indians here being a Indian yourself.My advise to is as below..
1. Swap your room with that lady.
2. Go away to some bachelor area away where any family with kids stays.
3.Do yoga yo control your temper and get habitual of kids playing sounds.
4.Make friendship with those kids and give them chocolate.
5. Listen to some kool music to get relaxed.
6. Ignore the sounds.
7.You have headache by kids play,you must consult a doctor.

I don't see why you have complained on QL

Thanks
