Every time A knocks on the main door she keeps holding on to the bolt and moving it across both the sides while we are waiting for the door to be opened.
And whenever the bolt reaches the other end due to which it gets locked within it, I keep explaining her that if she pushes the bolt further into it, then the door cannot open because it locks both the sides.
This action of hers and my explaining to her kept repeating every single time we knock on the door.
I never gave it a serious thought until two days back when I understood what A was actually trying to do when moving the bolt. If we actually ponder over what kids do, why they do and understand them while they do anything, their thinking actually amazes us. We ought to learn something from their behaviour. If my reaction to her action of moving the bolt was any one of - getting irritated, showing irritation in my tone, yelling for locking the door that way and wasting time - any of these, then I would not have understood her real intention behind what she was trying to do.
Just two days back, she managed to push the bolt to a little extent into the other end and told me what she noticed. That exact thing really surprised me. It was her urge to reach her goal that kept her trying every time she stood knocking on the door.
And, this is what she did each time we waited for the door to be opened.
The position of bolt right when we reach is this. Notice the length L1.
