Day Trip To My Favourite Thai Place

After editing 50gb of pictures, meeting with my supervisor and photographing Stafine's exhibition. I was very tired and hungry. I went to my favourite Thai restaurant to have my $8.50 lunch. Got home, Talked on the phone n a afternoon lab and off to photographing the concert.
Really do not understand why some photographers have to use flash in concert? why? their flash were point to the side of my lens and made most of my images over exposed!!!

p.s. no answer from the photographer i met yesterday
