Well, this is it. Dad can't swallow any meds, food, or water. So it's just a matter of time. My oldest brother is laid up with a bum leg after knee surgery a week or two ago, and the middle one is on a ski trip with his family; neither are likely to get here before he passes, but my younger brother lives in SJ and he will probably come up tomorrow.
Happily, my boss is totally cool about taking time for family issues (he lost both his parents within the space of a year, last year). Sister & I will be taking shifts, but we also have very good round-the-clock care; Dad won't be alone.
Goddamnit 2016, anyway.
