Weddings can be a total nightmare for anyone and everyone involved - whether you're organising the thing or simply turning up.
If you're a guest hoping to attend a friend or family member's special day, what should you avoid? What are the big 'no-no's?' and what are the common pitfalls?
Fortunately the good folks of reddit put their brains together to ask what you should ABSOLUTELY not do at a wedding.
There were anecdotes that raised fairly obvious lessons, like... Don't make a speech hinting to a secret relationship between yourself and the bride or groom.

Then there are a few tips that make you ask: "What on earth happened at this wedding?"
These are sitcom levels of awkwardness.

Don't criticise the person officiating the wedding.
Don't forget names if you're making an important speech.
And finally, just don't be this guy.
