In the 22 years we were together my in-laws never visited our home. My parents on the other hand surprised us once.
Thank goodness I was cleaning when I looked out the window and saw a car that looked like my parents. I went outside and looked as it drove down the street. It had OR plates, like my parents' car would. A few minutes later they pulled up.
I had my first gallbladder attack the night they left. My ex left the same day on work travel. I was exhausted. So, once the kids were asleep I hit the Ruffles and wine. Once the pain started I thought the kids(2, 2, 6 at the time) would wake up to find their mother dead on the living room floor.
