The difficulty is, a lot of the time a child's version of events is what they believe to be true, but actually, through an adult's eyes, isn't true, it is a distortion.
I have a class at the moment that is proving to be tricky (though improving). Several students went to their pastoral leader with a complaint that I was 'picking on' them and 'singling them out', because they had been told off for talking over me.
To them, because they are immature, being told off is the same as being picked on. If you asked them, 'Were you talking when Miss was talking?' they might say, 'Well, yes, but so was X.'
'Did X get told off?'
'Well, yes, but he didn't get a detention.'
'Was the detention for talking?'
'Yes'
Check back with the adult, and it turns out the detention is because the student was talking, received a warning, then was cheeky and back-chatting, then walked out of the room without permission.
'Did you walk out of class without permission ?'
'Yes but because she picks on me.'
Etc.
Students do sometimes distort things in their heads.
