Week 16 - The party

I arrived at the venue for my friend's party, it wasn’t familiar. I walked down a corridor with doors on either side. I opened the first door and walked straight in. There was no one that I recognised, I turned and left feeling embarrassed. Happily, the next door I tried revealed my friends although the birthday girl was not there. I continued down the corridor and tried door number three. I peeked in and saw some more friends but still no birthday girl. I looked in front and behind where could she be, which way should I go?
