In English it reads: “Generally speaking, the ones who know a little talk a lot and the ones who know a lot talk a little.”
Of course, someone like myself who prefers to sit and observe rather than speak non-stop is going to adore this quote, however, I find it’s true very often.
Sorry for the fuzzy image, I think it’s not as clear because it’s a bit of a long quote – I need a bigger board! French boy recently asked what ever shall I do when we move to another a flat – I said I’m taking it with me!!
