What a blandly stupid post. Imagine the person you write to, who got fired and is now worrying about their job prospects, kid's school, house payments etc, and other practical things, getting some saccharine note of half-baked "concern" in which you start with describing their having their ass having been canned as "parting ways".
This kind of neutered corporate-speak has invasively permeated every level of modern business, government and organization discourse, it's downright revolting to see it also drain down into informal personal communication from one human being to another.
