What's that called again, I forget...scatter brain?

Well! A half hour after I got to work I looked down at my desk, slightly to the right, and saw a full mug of tea. I remembered filling and turning on the water boiler, but I thought that I'd forgotten to finish the process of brewing tea after coming back from the men's room, as usual. I touched the mug and was surprised to find it hot (sometimes I find a cup of tea around from yesterday if I had to rush out). I thought, "did someone make me tea while I was in the can? That would be nice, but who did that?" I thought about asking my colleague who'd just come in, but was afraid to look like a dunce. Instead I just thought really really hard, and finally remembered that I'd done it myself, after all, like five minutes ago. Oops!
