This happened a couple of days ago. For my birthday, my wife took me to London from the US. We were eating at an Italian restaurant in Kensington (with the most amazing focaccia bread I’ve ever had) and just as my food came, she pointed out that the handle of the fork curved in a weird way (like a side profile would make the whole thing look like an S).
I hadn’t yet picked up my fork. After she pointed that out, when I picked up the fork, my brain treated it like I had never touched a fork in my life. Every position I tried to hold it in felt weird and unfamiliar. When I tried to put the fork in the pasta and spin up a forkful, the angles of the fork’s handle turning in my hand were completely foreign. It didn’t really help that I was eating tagliatelle and so it needed some fork dexterity to actually get a bite in. I ended up with bits of bolognese on my shirt as I tried to pull the pasta out of the bowl and it snapped and sprung back at me.
It took me a good five minutes to feel like I was actually doing the thing I’ve been capable of doing for several decades now. FWIW, the meal was otherwise great. Shout out to Cacciari’s in South Kensington.
TL;DR: I got in my head about how forks work and forgot how to eat for a good couple of minutes.
