Have you ever gotten up on...say...a Sunday morning feeling like a little something is missing. Maybe part of your memory from Saturday night, one of your socks, perhaps your phone number? You wonder why your spouse is bringing you coffee and ibuprofen in bed--all with a funny little grin on his face (and you are thankful 'cuz he could be banging around and growling at you)? You close your eyes and have visions of laughter (yours and others--you think they were laughing with you) and friends. You look down and see scabs on your knee and have a vague remembrance of falling (from your spiky heels to the icy ground). You're not sure how you got in bed--or if anyone was there with you.
