I'm reminded of a lecture in Programming Parallel Systems (by Jens Riboe) at KTH, where a student stopped him after having scribbled a code example on the blackboard:

- What's that?
- ???
- That code you just wrote - what language is it?
- That? It's just pseudo-code
- Well, we only know Pascal!
- Pseudo-code is not an actual language, it's just a sketch of a program.
- But we haven't been taught pseudo-code; we know only Pascal.
- But you can't express this neatly in Pascal…
- That's the only language we've been taught.

Thanks for sharing your experience. :)
