March 25. 2018

Not so long ago, namely on March 1, 2018, I took one photo. As it turned out - very interesting and unusual.

When I was photographing, from the side of the Cross Island there was a very bright sun and it was not quite clear what happened in the photo. Later, when I saw the result, I thought - not a bad photo and posted it on Instagram.

As they say - glad and forgot. But after a while my photo someone added to Picaba (or maybe somewhere before it was published) and the epic began with likes, messages and other attributes of a famous person.

But this did not last long, and I again live the life of an ordinary person, with which I am completely satisfied! Since in addition to the pleasant messages, they say a beautiful photo, there were also not very pleasant ones from the envious and other poor, they say I steal other people's photos, although such messages only amused me.
