The problem is you are dealing with a guy who is going to try and take the best portrait of you that you've ever seen. Every time. With no regards to what you paid or didn't pay, who you have or haven't shot with, whether you came super late or super early. Because if you've trusted me to do so then you deserve that effort. We both do. When the "likes" stop, the comments "dwindle", and the shares are no-longer I want you to look at one of my portraits and say; "That's me."
There's my why.
