Haha so much fun defiantly going to convince my friends to join me on this!
Love is fun, and it's more fun to celebrate with strangers you hardly know. To witness the love and celebration between two people and their family would be beautiful.
I would do this with only pure good nature intentions. I would be polite and bring a considerible gift. Act like I know the couple well. Have an awesome time. Would never crash a funeral... that is to me very disgraceful.
