Hi L2L,

Just a bit worried you might have your hopes up a bit too high - for the short term at least.

"I get the feelin that once he is truly alone... (no roommates..) that he will see things differently."

From my experience (limited as it is) he won't tell you even if he does have doubts about the merit of his decision.

And yes:
"He seems to bounce between sanity and alien behavior pretty quickly..."

Absolutely, but the sanity often becomes less and less frequent in the short term.

Just saying, be prepared for the long haul here.
