That's just the way things are in the world, sometimes there's no need to take them too seriously.
Those who can understand will naturally do so, and the old lady certainly knew what was going on. The wedding was just a formality and hadn't gained public recognition; they didn't even know, but that didn't matter as long as the couple was sincere.
A wedding isn't complete without blessings, and she, as an elder, bestowed just that on the newlyweds.
They bowed and paid respects to each other as husband and wife. Except for the absence of a room full of guests, everything else that was necessary was present.
The old lady was so happy she couldn't stop smiling; she said it was the happiest moment of her life.
Then they entered the bridal chamber.
