People take photos during travel. It is that essential because photos are all equivalent to memories. Either good or bad, beautiful or ugly. They are all the memories which you want to keep for the rest of your life!
For people who is having short term memory here, photos are so important in the sense that they are a part of your brain which stores memories. You see, photos act as a memory USB for your past, and to me, every past is a great experience!
The only reason that I posted this post, is due to the lost of all and each and every photos during traveling for the past years. And I am not over it.
I am still super not over it.
