My inability to make tea

I think I mentioned that Sarah spent the majority of the first trimester nauseated. Lots of different things set her off. She had to eat right after waking up, to the point where she kept a bag of almonds in her bedside drawer. Sweet things turned her stomach, ditto anything acidic, and coffee quickly became a no-no. So, her morning coffee was replaced by water. Later in the summer after the nausea went away for good, she caught a cold. Morning tea came into regular rotation, and even after she kicked her cold, tea was still in demand. Which became my duty. I set the coffee machine, I get up first. So every morning when she was sick she would say, "Can you put the kettle on?" Getting the kettle on and making tea adds about fourteen seconds to my morning routine, so in theory it shouldn't be a problem. Except that it is. Because unless I'm specifically asked, I can almost never remember to do it. I think it's because I've established a routine and followed it for the past four years, and now a tiny tweak to that routine just does not compute. If Sarah doesn't ask my to do it as I'm crawling out of bed, there's only about a 15% chance that I'll actually remember. And even if she doesn't tell me, there's still a pretty good chance of failure. Today, I was all proud of myself for remembering to fill the kettle, but then I didn't actually turn on the stove. TEA FAIL!
