Serial self-photo addicts are the worst. When humanity gets studied in 5000 years the 2000′s will be known as the age of the self-photo. We are all to blame, but for the most part I blame smart people. The ones who invented cell phones with cameras and texting , Facebook, Instagram and Twitter. We are a vain ass society and now every ding-dong is equipped with next level tools! Give us a shiny object and we will use it to enjoy our own reflection. Your man is at the forefront of that sh*t. You have every right to think it’s ridiculous. It’s your pre-2000 brain reminding you of what is normal.
Who needs to see him mugging for his phone on the highway, returning sneakers at the mall, at the gas station, on the way to work, waking up from a nap, popping a zit, etc.
Your question is “what’s the reason?” The answer is, he wants to communicate he is thinking about you AND he feels good about himself (or doesn’t, but wants you to think he feels good about himself). It’s a cheap and tiresome way to say “hey, girl”. I wonder if this vanity shows up in other aspects of his personality. If I were you I’d start asking for sweet texts or poems instead. Simply put: Tell him to shoot from the heart not the face.
