If you live in a country where the rules are that people do not talk to each other, you end up interpreting it that way too, no matter how much you would like it to be different.
And so if someone starts talking to you, as much as you like the idea, you might feel awkward because that goes against the rules, and therefore you interpret that there must be something wrong with that person, so you try to avoid them.
And even if you don't see it that way, even if you are glad that they're talking to you, you might automatically respond with aloofness simply because you're not used to it.
This is why it's so important to live in a country where the rules are as you'd want them to be in the first place, so that when someone does talk to you, you'll know it's normal and you won't think the person is weird, and you'll know that it's something you're going to have to get used to and adapt to.
And you'll be glad, because it will bring out the best in you, even though maybe at first it will be strange.
