yea anon is right, you did waste her time as she was at the door waiting and looking for you!
you should text her to say sorry, and explain what happened and why you thought it was best she didn't see you as you had a few beers in you!

aren't you glad you didn't go, because with a few beers in you, you would have dived into that pussy that hadn't been washed, just a lick of a baby wipe if your lucky!
