What do you do when someone scolds your kid in front of you?

Even i also cannot tolerate. If the kid does any wrong they should not scold they should tell to the parents as parents are present there

No way, if the matter comes to that I become a real ....... and can go to any extent. That is not tolerable at all.

I will calmly listen their words and keep patience. I can tolerate and keep my anger inside

I have no kids. If I had, I would ask the person to make complaint to me about the kid instead of directly scolding. Right or wrong, only guardian or parent and nobody else can correct the kid.

One day I went to a fancy shop along with my kid to buy some decorative items. At first she tried to search everything.(you know kids of 2 years). I made her sit in a chair. Yet she not listening me. A girl (unmarried) began to scold her. I scolded my kid and keep her away from items. Yet, she didn't stop. Even before she attempting to take things, this girl began to burst out. I felt really bad as my kid was scared seeing this that she kept away from things.
I had purchased a lot of items. It was upstairs. She asked me to go downstairs and that she will come with those items after packing.
I told you, I was deeply hurt. So, after coming downstairs, I left the shop purchasing 1-2 things downstairs.
I really want those things. Yet, I left the shop.
Am sure, when she came down, she would get good scoldings from the owner because it is due to her ill treatment that I left shop without those selected items.
Let her get it. It's how I responded to her response to kids

It depends on who the person is and also what the circumstances are .My mother is perpetually screaming at my kids about eating,sleeping etc etc and none of us mind it...But as for others, I wouldnt want that to happen since I too never think of scolding others children..

There were times when unrelated elders of the locality used to play guardians at times much to the pleasure and total approval of our parents. Now the scenario has changed,now true guardians even fail to discharge their roles at times!

As you said there were times, yes, there were times when they used to do it in good faith and to amend the ways, now no one wants to get involved in such matters, they only would do it in their own children's favor. So the things have changed. Besides none wants to get involved in such matters.

i dont have kids but yes i have this feeling as once my little cousin brother was playing that time he was of 4-5years it was when i was in 9th standard and a girl scolded him and was favoring her little brother.i felt very bad and i fought with her.

actually its in our nature that if we scold our little ones or own child we dont feel bad but at the same time when others do that we feel really bad.
even in future im sure if anyone will do so i wont tolerate it.

I will say him that he is a child dont scold him. If he did not listen then I will kick him.

Scolding is not at all correct. scolding child will create bad impression.Then they will loose the respect on the person who is scolding. that to infront of parents and if the parent is not reacting then children will feel insulted and they never have respect in their minds for their parents.
