My friends in Dublin know how to party.
On Christmas Eve I was invited to "The Twelve Houses of Christmas" - which is exactly how it sounds.
It was student housing so the houses were located fairly close together and we spent two hours at each house which started from early afternoon.
Free beer, shots, etc....was a really good night, I should go visit them again soon. The standard house parties are just as crazy, my friend is a DJ so he would blast out the tunes while we're free to go crazy and have fun.
