I know there are several first-time parents of babies reading this blog, so let me tell you an immutable truth of parenting that you will almost certainly be needing within the next decade:
If (and I'm speaking purely hypthetically here, of course) one of your children (hypothetically) plops down next to you and (hypothetically) says something such as, "Hi, Mom. I just haven't gotten to sit and talk to you in a long time, and I'm just wondering, how are you doing? Did you have a good day?" then you may be sure that at least one of the following is true:
A) There is broken glass somewhere.
B) There is paint somewhere.
C) There is a report card somewhere.
D) There is a new Wii game coming out.
E) Someone's fist has "accidentally" drawn blood out of someone's nose.
F) Someone has hacked into the CIA homepage.
G) Someone has "accidentally" set your house on fire.
Do you have any you'd like to add?
