Shmiras Haloshon – I think so too. Which explains why she thinks she either has to get married young or be an older single. Apparently, she considers 20 to be young (which many would agree with), but 22 or 23 are already considered older singles. So that is why she feels her choices are to get married young or be an older single.
I suppose if she gets married at 21, she can avoid either situation, but you can’t plan things that precisely. 21 is probably the one age that no one would consider either young or an older single (unless you’re Chassidish or very modern).
