I lost the first one - hope this doesn't show up twice:

When we returned from dinner tonight I moaned that house was already a mess again (it was clean yesterday). DD11 said just one word:
It's true!! In our house it's almost pointless to stop the descent into disorder.

Next, DD pulled the ol' late night "Mom, I have a question." She began discussing what it would be like to live in a 2 dimensional world; what are dimensions, really; that some think there are 11 dimensions...... I then insisted it was time for sleep!!!
This is after she spent some time earlier discussing how some folk believe that time is not really linear,but all things happen at the same time. Our brains cannot fathom that so we perceive time as moving forward.
Sheesh. I so do not have my child's brain. I Googled the 11 string idea and found myself on "Physics Forum". Then DD11 came out of her bedroom saying she couldn't sleep so I had to carry her to bed and give her mommy pillows to help her sleep.
