Yeah.. I have an 'invite only policy' at my house. There's a couple of close friends that have keys and are welcome if they need a place to crash,housesit,ect..I still have never invited any neighbors to a party at my place for this exact reason. I'm friendly and help them with things if needed,but I don't want to be their 'friend'. My home is where I escape the madness of life(most days,because I also do 75% of my work from home). I'm single with 95% of my friends being married w/kids and they live across town, is also an added bonus.
