People who complain about people who take their picture, try to cover the camera, or hide their face behind their hands, a book, or some other nearby object, need to stop and think about what they are doing.
First of all, think about who is taking your picture. Is it a family member or friend? Why do they want to take your picture? Could it possibly be that they love, care about, or at the very least, sort of like you enough that they want to remember this time with you?
Unless you are a celebrity and the photographer is a paparazzi trying to make some money off your face, you should be flattered that someone thinks enough of you that they want to have a picture of you.
You are loved! That should make anyone smile and proud to have their picture taken!
P.S. This mini-rant is not directed at any single person. (There are lots of people I know like this) So if you feel like I’m talking to you, remember, I love you! Or at least, I sort of like you.
