When I was 20-21 and “underweight” (nothing serious, really – just my body height and body weight not yet being in sync with each other), I bought a ring.
By some reason I got one in a size a little bit too big, and a year and a half later I got it adjusted.
Now, 20+ years later, it no longer fits me (unless my finger is really cold), and I regret that I got it adjusted (for an extra cost, too!).
Maybe I should just keep the old one as a memory, and simply get myself another ring if I really want to wear one?
