My now-spouse, then-new-SO, proofread my thesis for grammar, clarity, etc. At the time, I had written my acknowledgments, but after the proofreading, I added a thanks to her to it at the end just before submitting it and finalizing it.
But, I was a bit careless, and my post-proofreading addition, designed to thank her for improving and checking my grammar, ... was a sentence fragment.
