I used to be a pretty good liar.
"Where the hell have you been"
"Well basically what happened is my phone ran out of battery and I lost my wallet so I couldn't get home from college, stayed at toms instead, got my wallet back though but all the moneys gone, anyway whats for tea?"
In other words, yeah me and some mates got lashed last night, did lots of class a drugs and have been camping out at burley lake.
I always found the trick was to ramble on for as long as possible then change the subject. Confuses people.
