My granddaughter Lily set the thin envelope with the university crest next to her fathers plate and said, Dad, since you brought up Grandpas fingernails, I need to tell everybody where I really spent last summer.
Greg thought his daughter had spent the summer at a finance internship in Chicago, the one he bragged about to his colleagues. She had not.
Lily opened the envelope. It was a letter from the Dean of Engineering at Purdue, congratulating her on switching her major from finance to mechanical engineering, and on the award her summer project had just won. The project was a restored engine. She had spent the summer in my garage, with me, learning to rebuild it by hand, the way I taught Greg before Greg decided grease was beneath him.
Greg thanked me for teaching him to go to college so he would not end up with grease under his fingernails. His own daughter spent her summer learning to love the grease, and won an award for it.
Lily told the table she had never been happier than those summer days in Grandpas garage, that an engine made sense to her in a way a spreadsheet never had, and that she wanted to build things with her hands like the men in her family always had.
Gregs wife had gone wide-eyed reading the text under the table. Greg went quiet in his vest.
I have fixed everything with an engine my whole life. I rebuilt my neighbors furnace in January when she could not afford the repairman. I never once was ashamed of my hands.
Now my granddaughter is not ashamed of hers either. She wears the grease like a badge, the way I always did, and she is going to be a better engineer than anybody in a vest.
Greg did not finish his toast. But he came out to the garage with us after pie, and he rolled up his dress-shirt sleeves, and for the first time in thirty years, my son got grease under his fingernails. It was the best Thanksgiving I can remember.
