I know this may sound like a strange question, but do you actually know your neighbors? Do you ever talk to them? My neighbors are mostly elderly people who keep to themselves and, besides the "buon giorno", there's not much we say to each other. I even remember my friend being threatened by an old lady, he only wanted to ask if there's a key to the basement and the old lady threatened she'll call the police if he doesn't go away! Is this normal or are the elderly just scared of new people?
