The proverb I'm thinking about a proverb(observation) that say Russian. It sounds like "If you don't know what to say- say nothing, you will look smarter". That says to people with whom don't want communicate (? without want communicate). I think it's not fair because each person have a right of saying. So, it's important to say what you want in the learning of new language and even though your conversations sound like childrens' stupidities you needn't be shiing.
