3. My cousin was a wedding photographer who proactively offered to shoot my wedding for free. He offered about 18 months before the date.

About six weeks beforehand, he contacted me to say he was so sorry, but he’d been scheduled for hand surgery on the day of my wedding. I told him it was no problem as I didn’t want him to feel bad, hope the surgery goes well, and managed to locate another photographer at almost no notice.
A few months later, I looked at his website to see he shot another wedding on my wedding date.
