haha here in our country there is a saying that people like to do things that are forbidden ๐ , maybe they are blind or they just don't care about the sign that is put up. as long as they can do what they want to do, I also get annoyed with people like that, as if they are entitled to do it even though it is forbidden. if you tell them that, they will get angry with you. ๐ฉ๐
you are so kind in the part where you explain to your child what is forbidden and I hope you also said that maybe the mothers who take pictures there are blind because there is a sign, they still do what they want ๐
