Before you have to walk down the aisle, there's a whole load of faffing involved, including such things as finding your dress, the venue and deciding which shade of Thulian pink (that's a real colour) you want for your centre pieces.
But, before even all of that, there's the engagement. Which, actually, is the fun part. You get to drink copious amounts of Prosecco and everyone loves you for it, instead of thinking you're a borderline alcoholic.
Not only that, you get to go on an engagement photo shoot, which basically means messing around with your other half while a photographer tells you to look into each other's eyes as if you love each other, which you do, so that's easy.
However, there's one tiny snag - you probably won't get Bill Murray gatecrashing your engagement shoot like one couple from Charleston did, so already they'll never be a good as these.
The newly-engaged pair, Ashley Donald and Erik Rogers were quietly posing downtown along the streets in Charleston when the Ghostbusters star suddenly appeared.
According to the photography company who shot the couple, Fia Forever, the actor was "standing there with his shirt pulled up and belly proudly on display which he [patted] pretty loudly in an attempt to make the couple laugh".
"Needless to say [we were] stunned and [we] invited Mr. Murray to join the couple for a quick shot – He obliged and congratulated them and went on his way… leaving behind an extremely happy couple and this photo that will be forever remembered by this couple (and us!!!)."
Take a look at the brilliant image below.
