One day, I noticed a common thing in our apartment lift and the train's toilet. These are scribbles on the wall. Both, in form of words, and in form of sketches. The same obscene remarks and sketches. c**t, b** and several similar ones.
The train's toilets, or any toilet, are private areas. On the other hand, more than one person use the lift at a time. Then, when these scribblers get enough time to perform this special art.
Why do they write on the wall? Is it some form of sexual pleasure they enjoy? The graffiti of this kind possess some secrets, any way.
