My first reaction is pure anger...
How dare the JW's continue this bullshit shunning in the light of a family emergency! My second thought is that ToesUp is right: your wife is your primary concern and this JW stuff needs to take a back burner. Really, does it matter that much? This is your wife... she is sick - gravely ill... your mom is helping not them. grrrrr
Tell these nosey idiots to take a hike. Stand up for your mom and stand up for your wife.
-calms down-
and, i am so very sorry you are going through this. my thoughts are with you. hopefully your wife will heal well and quickly. <3
