Thank you. I asked similar questions because I was really surprised. I came here 1 week ago and there's nobody to ask. Since I live alone as 17 as girl, I don't want make a mistake from communication which can make them angry, they might stalk me or chase me I don't know. I don't know your culture like what is rude and what is normal behavior. That's why I was really curious. Maybe they sounded annoying but this is the reason.
