As Mother was telling me what to (and what not to) say, I talked to Whatagreatguy on the phone this morning. It was a good conversation, but it angers me that my overbearing Mother ruined any good feeling I might have come away with, and I can't 'roll around in' any joy I might have felt from the prospects of going back to work for the company I love. Anyway, here is the follow-up email I sent to Whatagreatguy:

At one point I had to ask him to hold on because Mother was insistant that I ask if I would get the next truck - something I absolutely would not put him on the spot about on the phone. He did ask me if I was still getting the unemployment (he wanted to know that I still had some form of income, which I thought was significant.)
He told me they had bought some, not new, but newer trucks, and that they were bringing some of the older trucks out of retirement. He told me people were shuffling around to fill the newer trucks (meaning those with more seniority would get those first) and that things were all up in the air at AMX right now. And he told me to check back with him on Friday.
I did ask him if there was any reason they weren't hiring me back. He said he hadn't checked with Operations (dispatch, load planning, etc.) but that he wasn't worried about them (as if to say he had the final say anyway). I had thought that maybe my heart condition (my stent) was causing them to think twice about me, but now I know this isn't the case.
So I still believe they will call me back to work.
