<human>: Could you distill the essence of the text into 1-3 sentences?

Background:  Friend from college called and asked for a place to stay.  I've known him since he was a Freshman (I was a Sophomore).  He's still in undergrad, an hour away from where I live now.  He asked if he could get a place to stay for a few weeks.

The kid was pretty naive when I first met him - didn't understand the concept of sarcasm, and saw racism in a lot of things (we're sort of in the middle of White, bible-belt America, he came from a rural town, was adopted, and probably was the only person of his race in the whole town, so I can see how that could happen).  He was raised in a very religious family, and is very religious himself.  Also, I know that he can be very, very, very high-strung.

Finally, he didn't really want to mention why he needed a place to stay.  The need isn't immediate, I guess, won't be until after the new year, but he's trying to set things up in advance.

So my question and
<bot>: Friend asking for place to stay.  Got any advice on what issues to be aware of with friends needing a place to stay, and how to avoid them/minimize them?
