When realization hits you like a ton of something heavy

When I was little, someone asked me, "which weighs more, a pound of sand or a pound of water?" And I thought really long and hard and decided water. It took even longer for it to be explained to me that a pound of something WAS THE SAME WEIGHT as a pound of something else. Sometimes I just get caught up in the details and TOTALLY miss the big picture.

Kinda like how this post is supposed to be about realizations and I'm nattering on about weight measurements.

Anyway, two days ago I noticed that I had a rather large lump on my head. My husband had a peek and said, my god woman, you've been bleeding, how the hell did you do this? And for the life of me, I couldn't remember. I'm pretty bad about stuff like this, I often have odd unexplained bruises on my legs from where I walk into things when I'm not paying attention or on my arms (which look an awful lot like defensive injuries) from leaning on my desk at a bad angle for a long period of time and stoically refusing to give into the pain and move them (and then being shocked, SHOCKED I tell you, to see that it left a mark)! If I ever end up in the hospital from one of my rather insane mishaps, he'll probably be arrested for spousal abuse. But I didn't have any other unexplained bruises, so it's not like I knocked myself unconscious somewhere. You'd expect there to be some bruising if I fell unconscious to the floor, right? Eventually we came to the conclusion that I must have hit my head while I was concentrating on something else, probably when I was under the bed, retrieving stashed clothing.

But not ten minutes ago, as I went to sit down and call my best friend, I scraped my head against the ceiling (slanted ceilings, we live in the attic) as I tried to avoid the piles of research on the floor, couch, desk, bookshelf, and table. Trying not to knock these things over, while holding the phone in one hand is a recipe for some kind of disaster. And as soon as a whacked my head, a few light bulbs came on. They said:
1) ouch!
2) ah, now I remember doing this two days ago!
3) hey, is that leftover popcorn?

So the mystery was solved, I now remember how I hurt my head. Of course, now my head is hurting AGAIN so that sucks. There isn't any blood on the ceiling... which is almost a shame seeing how hard I whacked it. And that WAS popcorn, but it was stale, thanks for asking. Meanwhile, I have GOT to try to remember to maneuver myself a little more carefully in the future... or at least the next week so my head can heal.
