Another night spent in library for essays. Thank god friends can always be by your side. We shared ideas with each other and somehow got hungry. One of my friends called the take out for a restaurant. Though it was not good to eat in the library. (We cleaned up after.) Selfies are one of the essential things we create. They record the happy moments of our lives. When we get old, these pictures can be much more precious. They are like the history of you. We can even share them with our kids and grandkids.
