I was attending a couple of days ago quite a specialised course (STEM area) and a topic of the importance of communication came up. It is indeed an area where many people lack "softer" skills - i.e. they can do the technical bits, but can't then explain the significance of results to a non-specialist.
The lecturer said "I always say to my students - you need to be able to explain it in such simple terms so that your mum could understand".
It rubbed me the wrong way a little bit. Why not "that your dad could understand"? The audience (as much as I could tell from the online meeting) was indeed young (early 20s) and overwhelmingly male, but there were a few of old hags (and mums) like myself attending as well, and a couple of younger women too.
I am not the one to be mortally offended by any slip of the tongue, but would I be unreasonable to ping a private message to the lecturer to suggest that may be there could be a better analogy he could use next time? Or would it be totally OTT?
