Good things come in threes for the happy couple's nuptials

It turns out when your sister gets married for the third time the exchanging of vows comes with a sibling code of conduct.

This mainly revolves around not making any reference to the wedding marking a hat-trick of Big Days for the blushing bride.

No quips about her tying the knot more times than a Boy Scout or changing her name more often than Prince.

Not a mention of having more toasts than a builder's breakfast.

Even innocuous questions like, 'did you go to your usual bakers for the wedding cake?' are on the banned list.

Which is all a bit tricky when one of the main jobs of a big brother is to spend your life taking the mickey out of your little sister.
