My mother says something similar to the top half of this to me from time to time. And everytime she does, I groan, because I'm a teen, so "I know". But the top half of this verifies the second half, so at the same time I'm groaning, I inwardly smile. Because this, and the truth behind it, is one of the greatest examples of how much she cares. :)
Not a parent, but I can understand the sentiment..
