Judging by the latest picture of Barb and Anna, I doubt Barb will be alive this time next year.
She doesn't look drastically unhealthy, but the weight loss is dramatic and goes way beyond "Welp, can't afford as many Big Macs as she used to."
She's literally wasting away from the looks of it, something that Chris seems blissfully unaware of.
As anyone who worked at a hospital or nursing home can attest to, its not the jolly, fat 70 year old you expect to kick the bucket. It's the 70 year old who've lost 30-40 pounds over the last year, who suddenly gets a trivial infection, and is dead two weeks later.
The latest picture of Barb and Anna makes me wonder if Anna would step up to the plate after Barbs passing.
Not that Barb necessarily is trying to rope her in to take care of Chris after she's gone, but the sight of a devastated man child trying to deal with the practicalities of a death in the family (and possibly the Facebook asspats included) could be enough to motivate her.
