I hate it when I leave the house without something important like my wallet. I am a creature of habit to the extreme. Every night I come home from work and unload my pockets. Wallet, checkbook, spare change, knife, pen, watch, cell phone, and about 5 key rings all go on a side table. Gun stays on and when it is bed time, my gun goes with me and stays on the wife's bedside table while I keep the 12 gauge on my side. In the morning, I do it in reverse, with my last stop before walking out the door being the side table where I left my wallet and various other items. As a single man, I never forgot anything. Marriage changes things though.
Every once in awhile, for reasons unknown, my wife with tidy up and move some of the stuff off the table like my pen, or watch, or cell phone. Once any item has been removed from the table, I will always forget it. Then about an hour later when I reach for my pen, or look down at my watch, I discover I don't have it. I don't know what frustrates me more, my wife moving it in the first place, or the fact that my brain is unable to notice it is missing before I actually need it later in the day.

“While the people are virtuous they cannot be subdued; but when once they lose their virtue then will be ready to surrender their liberties to the first external or internal invader.” ― Samuel Adams
