How can I avoid talking to a neighbor I do not wish to speak to?

dude calm down....that's just plain stupid.Its not worth thinking about or asking on here about. just don't. don't think about it. don't talk to them. just be and go on with your life. politely refuse to mow they're lawn and if they insist then that's just plain annoying and immature on their part. be nice and just ignore them.
