I feel that we let people know how we expect to be treated by our treatment of others.
I look at children as humans, because they are! haha They are humans just like me, and we get to help form the world we live in by treating the young with respect and by showing them how to interact with others.
People who grew up with this "seen but not heard" mentality are most unfortunate in my mind. What's worse, I could see someone who was belittled in this way during their childhood, growing up seeking a place of power over children, like a teacher. Not that all teachers are power hungry, damaged former youths, I've known some incredible humans that chose that path with the intention to help children learn, but since compulsory schooling is a sick system, sick people no doubt gravitate there.
Thank you @canadian-coconut for speaking out, yet again. I do feel better about the chances of turning this world around knowing that there are wonderful people like you out there!
