Okay, they really _are_ that yikesy likesy, but they never say 'um' - 'like' has replaced it.
They are also intelligent and observant. Much of their conversation revolves around family and friends, and the strange land called the past - where their parents live.
I recall having exactly the same conversation when I was a youth - I think it is a mandatory deliverable of childhood. I had a very rough day - they made me smile the whole way home.
So, thanks, anonymous young ladies enjoying life. :)
