This was me back when I was about 2 and not much has changed. (In fact my nokia phone is pretty similar to the one in the photo...)
The more I talk to people, the more I discover that I'm not the only one pretending to be a grown up. I'm not the only one feeling really unconfident but seeming totally confident.
Even the wisest of teachers - I have heard them say similar things.
People are funny.
I love them all the same.
