There's already so much that can go wrong at weddings, so at the very least, it should be guaranteed that the people getting married do, in fact, love each other.
People on Reddit shared stories of moments they saw at weddings that spelled doom for the couple, which statistically, happens A LOT.
At my brother's (first) wedding, my Grandma apparently saw a brief exchange of looks between the bride and her boss. She kept her mouth shut and sure enough, within the year, they were divorced, Bride was f*cking her boss.
When the hotel had to at the last minute organise a seperate room for the newly married man.
The wedding couple came to see me about a month in advance of the ceremony to choose music for the occasion.
They couldn't agree about anything - from the processional to the recessional, and everything in between. She wanted the organ to be soft as she entered - he wanted the organ to be big and "triumphant" (his words).
