[The Queen]

Whatever the truth was hard and will hurt just say it... Saying the truth eventhough it hurts is much better than lying... w "7abel el kezeb 2assir"...
For the age enno even if a kid asked such a question u should be honest with him of course in a way that will make him accept the truth and understand it easily... and as blyblu-dima said a 3 years old kid won't ask u such questions... and if he asked he has to know the truth cuz he'll know it sooner or later, which won't make a big difference if ur way of telling him it is gd...
So we just have to know how to tell the truth...
