Once upon a time, there were two couples: Sue & Tom, and Gary & Linda. Sue was the Hall Director for a all girls dorm at Central Michigan University and Gary was the Hall Director for the corresponding all boys dorm. Magically, Sue and Linda are both pregnant at the same time - and both couples have girls 3 months apart -- the first (and only!) child for both. Welcome Carrie and Amy! Carrie and Amy lived the first couple years of their lives in the dorms - surrounded by lots of college students (built in babysitters).
From there, Sue & Gary both got promoted to each manage 1/2 of the CMU Residence Halls. So both families move off campus, but because Sue/Gary work together and both couples have little girls about the same age -- they still spend essentially every weekend together. The couples combine babysitters and social circles.
Even though the girls don't end up going to school together until Jr High, they are always friends. During one summer, Carrie and Amy decide that they will: move out together (at 16), buy a car together and then live on the same block with their families.
After college, Amy buys her first car (a lovely 1992 black Grand Am - too cute!) and then 6 months later gets a job with a company car (a 1993 maroon Taurus wagon, not so cute, but free!). So she sells the precious car to Carrie's dad Gary to use the $$ as a down payment on a condo. Two years later, Carrie moves in and is now driving the aforementioned black Grand Am. Live together? Check. Share a car? Check. Ok -- so we weren't 16!!
After living together, Amy introduces Carrie to her cousin Barry. Eventually, after a few years of dating, Carrie and Barry get married and have a little girl - Mary. Now with the timing of Amy's adoption -- the two could have kids about the same age. How cute is that!!
So long story short, she's probably the closest thing to a sister I have! Enjoy your week -- I hope to have some GREAT news later this week!
