I think I'm turning into my mother.
Now, I should clarify I like my mother. A lot. There are great many characteristics of hers that I should like to emulate. Her sleeping habits are not one of them.
When I was a teenager my mum could never seem to sleep an entire night. She would wake anywhere between 2am and 4am and look at the ceiling for hours. I couldn't understand it. She was tired... nay, she was exhausted. She worked for both love, caring for 4 children, and money, in a job she enjoyed. I considered her sleeping issues ridiculous. And perhaps evidence of a character flaw.
I've changed my mind.
