how to tell people you are moving into a van

i've had this experience a few times now where i tell someone i'm moving out of my house, they ask "where are you moving to?" and i say one of several things--"oh i don't know" to which most react with a confused/disbelieving look and a need for more explanation. or "i'm gonna stay with my boyfriend for a while" which is a lie, and i feel bad about because i'm trying for radical honesty and this ain't it. or "i'm going to live in my van" which brings a host of responses like--what?!, uh..., (blank stare), oh you are out of your mind, ok..., but where will you shower/poop/park etc., do you need a place to stay?, are you in desperate circumstances? then i feel like i have to launch into a diatribe about how i'm CHOOSING to van-dwell, and i don't HAVE to and if i need something i'll call or get it or whatever. i'm on the defensive, i feel a little stupid, and it feels like i sprout 3 heads when i give an honest answer. most people think that not having a stick house=homeless. and that is a bad thing in their eyes--maybe it's their worst fear. my worst fear, however, is being trapped in a bunch of debt with no end in sight, never being able to travel or take time off, and working my whole life away at a job i don't care about. i feel the american dream is a big fat lie meant to keep the majority too busy to notice the insanity that's going down around them. if you work 50 hours a week or more to buy the toys you want to keep you busy in all your free time while the neighbors envy you, what time do you have to think about the purpose of your life? how do you know what is real or important? when it comes down to it, is what you spend your time on that significant? i think it should be--and i want to spend less time making money, more time learning what i want to learn, going where i want to go and experiencing people who inspire me. that's really it. that's the purpose of van life for me.
