I don't think she'd be the only one forgetting to do so, it's quite human (I believe we're all able to do so, depending on amount of stress and so on), so if that was enough to level Marriott there wouldn't be a Marriott hotel standing anywhere.

Ok, so maybe her clumsiness is actually a divine kickstart of events waiting to happen? Well, as long as it doesn't interfere in her having a wonderful, long, happy life I guess it's ok...
