Where do your thoughts live?

Thoughts come and go.  We may not like all that check in, but we surely don’t have the vacancy problem in our heads.  Some hosts attempt to screen their thoughts by turning away grumpy and disruptive guests.  Others welcome them all but hope that the good ones stay longer.  Still others are in danger of being overrun by a bunch of negative characters who move in, invite their friends and have a party in complete disregard of their hosts’ sensibilities.   

How do you enforce your house policies?   What kind of place would you want to run and what guests do you want to attract?  Do you like to engage in thinking that is formal, casual, modern, eclectic, or traditional?
