Sisters A, B, C, D, and E will be at the Metro between 10:15 and 10:30 am Sunday. Each has a bag with her. Sister A lives locally, Sisters B, C, D, and E need to be transported to the airport. If Husband F drives to the Metro to pick them up, one person and one bag will not fit in the car. Daughter G lives near the airport and will be going to brunch near the Metro at 11:00 am. If she drives a second car to the Metro, everyone will fit in a car, but G will be late for brunch, and will have to do a lot of driving. Also, G's car is uncomfortable for adults to get in and out of the back seat . . .
And so on. Right now, I am thinking that I should have Sharif drive me to my parent's house that morning. I can then get the keys to Mom's car, and the three of us (Me, Dad, Sharif) can each drive separately to the station. Then I pass Mom's car on to her, she and Dad split the sisters between them, and I get in Sharif's car and we head on to brunch. Whew. So complicated.
