You know, now that I think of it, my BFF said almost the exact same words to me. She said, "You are on your way to being even smaller than me" (she is "normal" sized). It didn't occur to me until reading your post now that it may have come from a place of insecurity? I don't remember it bothering me at the time though, I just took it as a statement of potential fact. I love her to death, and I know she loves me back so maybe that may have influenced my reaction (or non-reaction, I guess) when she said it.
Although I do seem to remember it pretty distinctly, so it must have probably hit some sort of something since I can remember it now, 2+ year later.
I have yet to date to receive any flat-out perceived snarky remarks form those I hold dear. I had however, got a few annoying words/comments from some extended family members at family parties pre-covid. But they are not very high on my love list so it didn't much matter to me....more of an annoyance vs. an injury.
But its been a while now since I've been this size, and its all par for the course now with all that I interact with. Like with most things, its just a matter of time getting used to a new normal.
