If you notice that I normally comment on your posts, don't be surprised, it is part of the culture of my country, to be sociable and kind. Here it is normal for us to start conversations with other people while we wait in line at the supermarket or at the pharmacy, or while we wait for someone... (we start talking to others in a short time as if we knew each other before when in reality we just met). That's totally normal! In fact, if we look at a neighbor in the morning or arrive at a place where there are people sitting, or when we arrive at any store, or get on a bus or wherever, we should say to people: Good morning (to all). or good afternoon (depends on the time of course). It's not difficult for us to make new friends!
