It's no surprise children would see you while adults can't.
This because children really are innocent. Right up until society and adults get their hands on them and brainwash them into believing the accepted norm... the accepted norm (which is slowly starting to change now, thankfully) is that something they can't see doesn't really exist, and if you talk about it in public you'll get ridiculed for it. Nobody wants to be publically ridiculed!
So children eventually grow up and stop "seeing" the things that adults don't see because it's taught... it's really caused humanity to forget a lot of things. Sadly...
