Once I was visiting Cappadocia, in Turkey, I went to a Bazaar in a nearby town, where only locals go, not tourists. I bought some things in one of the stores and the owner invited us to take tea with them. We accepted, and two minutes later, he invited us to eat with them, behind the stall.
He and his collaborators set up a small table with chairs (everything was completely improvised), and these kind men shared their food with us; we wanted to say no, but we found that would be rude. All this happened without knowing a word of any of the languages we spoke; we understood each other by body language.
As human beings, we can understand one another without needing to speak the same language!
