This one used to bother me SO much. I’d peruse the obits and shake my head, making remarks while reading: ”...she went to be with her Lord…” “He is with his eternal blah, blah.”
Then, one day it hit me. Why did it bother me so much? This is probably the last time these folks are going to have ANYthing written about them. What does it matter whether they say Aunt Martha is going to fly off with the neighbor’s pigs?
Doesn’t bother me anymore.
As far as other euphemisms…there are people who don’t find it necessary or appropriate to “tell it like it is”. And, usually, they’re shocked when someone else restates it less delicately.
