I swatted a fly and the exact day and time I did it is tattooed on my friends ankle

I was on the phone with my friend who has a fly tattooed on her ankle. I swatted a fly and she remembered something about the tattoo. When I asked her what was up with it she said it was done by her ex who was a tattoo artist. He said he wanted to do a special tattoo in memory of their relationship and the time they spent together. So he did the fly tattoo. I was swatting at a fly at the exact time he was doing the tattoo and my friend remembered me saying “oh shit I just swatted a fly.” He wrote down the date and time somewhere on the tattoo that only they would know.
