Nate's P-days are Saturdays.  We got another short email from him last Saturday, September 9, 2017:

I'm fine in here. We stay busy so it's okay. I live on the top floor of the residence, so I take lots of stairs every day. My classes are in the new building and it's all very nice. The MTC is okay, but I'd rather be in the field, but I also know I'm not ready for that yet.
