As you do when you are getting married.
So guess who's not doing any work today? And celebrates, again, instead?
Because finding someone you can talk to, and laugh with, and share all your ups and downs with; someone who copes with your small and large faults and peculiarities; someone who is happy when you are and would like to lift you up when you are down - finding someone like this is the greatest thing on this planet, and it should be appreciated and cherished day by day.
Obviously you can't have a party every day because of it. But you definitely can once in a while. Also a great reason for having some cake! (If you need a reason for cake, that is...)
