For three years, my husband spent every Friday at my sister Karen’s house. He always had the same excuse. Then something didn’t add up.

heavy weight settled deep in my chest. I need to back up for a second.

To understand why this hurt so badly, you have to know about the plumbing drama. It started on a Friday in October 3 years ago. Karen called our house crying.

She had just finalized her divorce from her wealthy husband, and she was living in a modest ranch home on Oak Street.

She said her kitchen sink was backing up and she couldn’t afford a real plumber. Mark immediately volunteered to help.

He was always the quiet, reliable type. He went to his garage, packed his gray metal toolbox, and drove over.

He came home 3 hours later, smelling like pipe grease and copper. He told me the pipes were ancient.

He said they would need weekly maintenance until we could afford to help her replace them.

I thought he was being a wonderful brother-in-law. I felt proud to be married to a man who cared so much about family.

Every Friday, the routine was the same. Mark would come home from the warehouse, grab his toolbox, and head to Karen’s.

It became a joke in our family. At Thanksgiving, my aunt even asked if Karen’s house was built on a swamp.

Mark just smiled his quiet, Midwestern smile and said old copper pipes are a nightmare.
