If Anna didn't eat her omelet, who did or flushed it down the john??
Someone taught me that make some kind of event....REALLY BIG....and no one will notice the other possibility.
Consider the omelet as REAL BIG. An omelet has "footsteps", too.
What would be REALLY BIG about the omelette? Are we supposed to believe that cuz they say she ate an omelette at 11 oclock, that she was alive at 11 oclock? Is that what you mean? (sorry, slow little grey cells today)
