Well he's still tired but I think with this weekend off he should recover some! School is off tomorrow and with today off, I hope that does the job! He probably won't be completely over everything, but the worst...
My in-laws have been there since 68...in Paulinia near Sao Paulo. They are independent missionaries but went down with the Menonite church... They are retired now, but still active in the community. My MIL teaches English. I think they will probably not come back to the states permanently. Everybody asks me that

That is so neat... It is amazing to meet people who have connections there!
