Hehe, in my case, it's that sometimes they have to join in conversations where they only understand half of it.
For example:
- "This color feels too heavy to me, it overwhelms everything - what light color would be a good counterbalance? And would the harmony still be right?"
Or:
- "The proportions aren't right! - Should I make the balls with the 6-row or the 7-row? But if I make this one bigger here, then I have to adjust everything else too!"
Or they are expected to be able to give informed answers or advice on topics like:
- "What do you think, what's better in summer, a cotton/polyacrylic blend or maybe something with silk after all? And what do you actually think of viscose? .... Or maybe kapok instead?" :-D
Oh dear! Sometimes I do feel sorry for them! ;-) ..... Luckily, I can also listen to their topics (painting, philosophy, or cultural journalism) and try to put myself into those subjects ...
