I like the vulnerability displayed by the author. I'll share a moment myself:

A few years ago I was the TL on a FAANG Android project, where for a few months I was doing more spreadsheet/TPM work than usual, and didn't have much time for coding. Once we had a meeting where I ended up coding in Kotlin live in front of a dozen younger devs to discuss the implementation of some feature. My work background is Android and Java/Kotlin, but at the time I was mostly coding in C on the side, and in the moment my brain just forgot what the syntax in Kotlin is for a "switch-case" statement, so I wrote "switch", "match", etc, struggling like a first year student, while everyone watched me fumble, until I just gave up and said: "oh my god, I'm forgetting Kotlin. What the hell is the switch keyword in Kotlin called?". Then someone said: "it's when".

I felt old and a little embarrassed, but mostly I was surprised at how quickly I could forget a programming language I used daily.
