Keep-out house

This poem by Shel Silverstein reminds me the time that we want to be just by ourselves so that, we can hardly find our own selves,

At last-I finished my keep-out house,
A house that's meant for privacy,
A house that's meant for peacefulness,
A house just meant for only me.
There is no door where strangers knock,
No window where they peek and grin.
A perfect private keep-out house...
Now ... how do I get in?
