I like this because it touches on the appeal of Snapchat: its ability to become quick reminders of the people around you. Barrett sends me some of the greatest, most hilarious, most endearing Snapchats and even if I haven’t seen him in a couple of weeks, I am reminded of why he is such a great friend. They can act as quick, visual messages that resonate more than a text message and a phone call because they won’t last. That’s the key. By opening it, you are acknowledging that it won’t last forever, that you have settled in for this quick moment and that it will be gone.
