Theory:

Don’t pick your nose
 
Sit up
Say please
Less noise
Explanation:
 
Children often tend to pick their nose as they are not aware of hygiene at a very young age. Picking one's nose can cause the spread of germs and may lead to infectious diseases. But children pick their noses subconsciously most often and it becomes a habit. They also do it when they are bored or when their mind is occupied with something. Adults could teach them hygienic habits and encourage them to raise the issue to the adults if they feel a nasal block.

Child picking nose
 
Children may experience tiredness or maybe lazy at times. They may slouch and be lethargic. It can be during a class or a prayer meeting. When parents have conversations that only people of their age understand, or if the children find a particular thing boring, then they tend to lie down or slouch. But they are asked to sit up straight and pay attention even if they do not get the purpose. When one needs something, it is always polite to use words like please, would you, etc. It is basic manners to be polite when one needs a favour. But children are encouraged to say 'please' even if it is not required. They are also not taught the purpose of the word. They are blindly made to say a few words which do not make sense to them. One must teach them that words like thank you, please, are meant to treat the other person as equal. It is not fair to order everyone around. But the adults who teach this, do not use the word please to the children to make them do things. Rather they themselves order them about with a to-do list.

Child slouching
 
As years pass, humans are becoming more intolerant. For example, children make noise and it is normal to some extent. Adults get impatient for these small events and order children to remain quiet. They can find a solution to distract them with other things to make them quiet, rather than bluntly asking them to remain silent.
