Facts of Life?

I'm in Utah right now, taking care of my Dad. He had a mountain biking accident and broke his hip. He's doing very well, but just has to hobble around on crutches and needs a little extra help doing things.
I dropped him off at a stake (church) meeting last night and went over to my sister's to see her and her husband and play with their five kids. I've really missed them! I had fun playing wii with my nephew Matt, watching Lucy take some of her first steps, and reading stories to Lizzie, Josh, and Sam. Josh and Sam (aka the "cage fighters") are true guys - i.e. tried the whole night to impress me and outdo eachother with their flatulence.
Anyway, when I put Lizzie to bed, she asked me to cuddle with her, so I lay down by her and we talked about whatever comes in to an 8-year-old girl's head right before she falls asleep. We started talking about wedding receptions and she told me how much she liked mine and remembered being on the boat. She then told me that she wanted to have a large reception so that she and her husband could sneak out in the middle and... (of course at this point, I was wondering what in the world she was going to say.) ... go to the slurpee store for slurpees! She then assured me that brides and grooms will sneak out of their wedding receptions to go get slurpees or candy. When I asked her how she knew that, she said she just listened carefully, like when her Mom was on the phone, and just found these things out.
Of course Lindsay, her Mom, denies any such phone conversation.
