A Letter to My Siblings

From a letter to my siblings (context is that my brother had described my father's new short(er) fuse and impatience):

For the record, I called a couple of days ago (Sunday or Monday), not today (July 4).

So what are the chances that there's something physical going on like thyroid or something?
And no I'm not volunteering to try to talk him into seeing a doctor based on the fact that he's acting crazy. Though in a way I almost wish he would act this way around me as then I would point blank tell him that he's acting like a maniacal caged animal. (Bet that would be a sight to watch - from a distance.)

By the way, any opinions on when I should come up to say hello to them? Something in between our August Whitney trip and ski season would work well (say Sept or Oct.).

PS Mother is intrigued with the restaurant that I took a group to for my birthday: Buca di Beppo. As you might guess, it took 15 minutes for me to spell it out to them.
While there are two in Washington (http://www.bucadibeppo.com/locations/default.aspx?state=WA) I can guarantee that Dad would hate, hate, hate it as they sort of encourage noisiness (it's great for groups). But just to note, the food is surprisingly good even bordering on excellent.
