Photos in new bathroom

I don^t know if you have similar friend to me but I have noticed something funny recently. There is plenty of people that I know whoa re taking pictures all the time. They walk with their camera all the time and wherever they are and whatever they are doing they take photos of this activity. I don^t know what you think about it but in my opinion that is funny. Why are they doing it? Later on they put it up on their photo blogs to make sure that everyone sees what they have been doing recently. Maybe they are doing it to show how interesting life they have and what is going on every day. They want other people to acknowledge it. Sometimes it is interesting as a matter of fact but on the other hand sometimes I find it difficult to understand their actions. Let me show you an example of it. I have seen a photo of my dear friends in their new bathroom. I have seen it on their photo blog so the rest of the world could take a look at it as well. What is the point of uploading that particular photo? Maybe you would be able to explain it to me because I find it abnormal. Would you do the same thing? Maybe you have similar friends and you can give me examples of even funnier photos?
