Assisted Living Facility. You'll find this forum rife with acronyms! NH - nursing home. DIL and SIL - daughter or son in law. MIL and FIL - mother or father in law. MC - memory care. I've seen some I don't know, though. DH - I can only assume is "dear husband." SNF is skilled nursing facility. Sadly, eventually, you'll come to learn them all if you're here. Whatever your situation, good luck.
