Well, in the UK anyone who is of “No Fixed Abode” is counted as homeless for legal, statistical and welfare purposes (you get lower benefits because you don’t have rent & bills to pay: it was £11 a week for a single male in 2002 [equivalent of $23.06US today correcting for inflation]). I was cycling round several different peoples houses because none of them could put up with me for more than three days in a row! (I was very angry, bitter and self-involved at that point)
Why ask if I’d been homeless though?
Sorry, your post was so similar to the OP that I asked the wrong person! I was wondering if the OP has been homeless.
