I wonder if we could have a "definition" of stealth boasting. I keep seeing accusations of it which I think are unwarranted.
My interpretation is, "while sitting on a gold chair in my luxury apartment in number one Hyde Park, my husband said he wanted to watch a different channel on the telly" is stealth boasting because it isn't relevant to the issue.
However, "as my house is very slightly larger, my I laws have decided that they are going to sell their house and move in with us" would not be stealth boasting as the size of house is relevant.
