To photograph the smile of people who describe themselves using the word 'smile' on their profile

Hi, (First name),
Hello, I'm Sayaka, artist, live in Berlin. The reason why I write this mail is not to ask you a couch but would like to ask you to be a model of my photo shooting. Project theme is ''To photograph the smile of people who describe themselves using the word 'smile' on their profile'' ...yes, I understand it might sound somehow weird, and that's why I've found you :) The shooting plan is very simple. I'll bring one compact digital camera which is able to release shutter automatically reacting people's smile. I'll set this camera with a tripod in your room, and would like to shoot your smile for 60 minutes by this automatic shutter system. I'll trip (city) from (date) to (date), if you are interested in participating in this project, or have any question, please feel free to send me a message. If you are not interested, please simply ignore this mail. Looking forward to your response, Sayaka
