What Happened?

Finally it's Friday, that means for you. Let's go to the bar. There you meet, twins. One is loud, proud and confident The other one is quiet, shy and sarcastic. You order your favourite drink and one of the twins orders a whole round. Then another And another After that you awake in your bed, one twin on your right, the other one on your left. You slowly get up, noticing that they are still asleep. Now what will you do? Find out what you did last night? Trying to do damage control? Or do you make the best out of it? The decision is yours.
