There are a few reasons why someone might reject a marriage proposal.
Maybe they fell out of love with the person popping the question; maybe they felt their relationship wasn't quite at the "marriage" point yet; or maybe they were proposed to by someone who had absolutely no business asking them for their hand in marriage.
But perhaps one of the most unreasonable excuses I've ever come across for a proposal rejection has to do with the ring. Or should I say, the "wrong" ring.
