I only regret things for a day or two... THen I add them to the list of entertaining things I do when drunk!
Recently: Kissing a dude on New year because there wern't enough girls around, and he was dressed as Big Ben!
Dropping the C bomb when refering to an ex in a status update... forgetting I hadn't deleted her mum or her friends yet...
Paying a tramp to play me a song on his guitar, and then paying him again to stop because he was shit! (Also, and easy way to lose 10 quid!)
Ending up in a Nigerian Bar in Warsaw, where I had a great time with the owners, and finally got a picture take with me and a mate kissing the cheeks of the owners mother! She didn't speak much English, but she looked like she loved the photo!
Loudly ranting to some Danish Girls I had just met in a cafe about how much Harry Potter sucks... Unfortunately drinking until 0400, and getting up at 0630 doesn't sober you up enough to function properly... I also no't think they were impressed... they did think I was hillarious though... Seems they thought I was joking! I WASN'T! THE BOOKS DO SUCK!
Regretted all of those at first... But hell no! Not now! (The photo pne was only a regret because I was tagged on facebook, and it was very dificult, and slightly awkward, to explain!)
