My advice is to stay in your room and lock the door, wherever you end up, and get back over the border as soon as etiquette allows. Stab proof vest and no speaky English accents are advisory should you need to exit your room. Have fun, it's only two days...Independence might soon be there
It's because of **** like this I have not attended a wedding in years, apart to place a bet as to when the whatsit hits the fan in the more ambitious (socially or ethnically disparate) pairings. Coupling couples and their next of kin have no sense of humour these days...Have fun
