Which box has my brain?

The wallpaper has been removed, the paint is dry, the majority of the furniture has been moved in.

Now I have some questions:

How can one move into a house with the same floorplan and have the furniture seem too big?
Did the cable guy lie to me when he said “Listen lady, if you want it installed today, the Internet service has to go right here.” (here being Grant’s room) “Otherwise you will need to reschedule and we can come back in about two weeks.”
Is instant gratification the reason I’m sitting on the floor of Grant’s room, balancing a keyboard on my knees and using a box of Legos as my mouse pad? (My ass says that next time we should reschedule and do it right.)
Why did previous residents make lots of nice upgrades, but all of them chose to leave the original, pinkish brown Rossmoor tiles & tub in the bathroom?
Why do boys who can run, jump and play all day long suddenly become soooooooooo tiiiiiiiiiiiiired when it’s time to unload a truck or carry their own damn toys to their rooms?
If I kept a clean house all of this time, why was there all sorts of guck and mung under the fridge when we moved it?
How long will the spice cabinet stay neat and orderly?
Why didn’t I find the missing Tupperware lids or the socks?
Why have I moved certain articles of clothing and shoes from California to Washington and back again… when I know I haven’t worn them and am not likely to?

and my big question…

If there are boxes that are still sealed up from a move made in 2002 (and I haven’t missed anything), should I open it or just continue to store it?
