Girls (not toddlers, class 4+- by the look of it) run around the corridors in their underpants and this is the norm for them.None of the teachers will even make remarks.But there are men among the teachers and there are a lot of boys around.
Teachers are not all friendly and in relation to children they allow themselves what they should not allow, including mats, insults to children and their families.Children can be left alone during the lesson and do whatever you want.
There are very few teachers who actually teach children.
There are cockroaches at school.It happens that children accidentally bring them home in backpacks.
If you are faced with a choice, it is better to choose another school.
