No way! The flowers are simply too beautiful not to be photographed or to be photographed with them myself)) Why look for meaning where there is none. Someone takes pictures of their cars, someone of children, and someone of flowers. Everyone has their own interests.
My friend can post a photo with flowers so that her new boyfriend can see that she was pleased with his attention. I can take a picture with lilacs or sunflowers in the background, because I really liked them. Once I was photographed against the background of the bouquet, because it was my first bouquet of flowers at the age of 16 and laid it out, although, of course, I could not have laid it out, but flipping through the tape, I see such memorable photos and I am pleased. If the photo does not convey the message "and the guys give me flowers, envy me!", Then I am okay and do not hang any labels on the girl.
By uploading a photo, whether it is a girl with donated flowers or a man with a new car, a person declares his status, which is determined by the subject of the demonstration itself.
The society evaluates the value of the demonstration, compares with its capabilities and evaluates itself either on the same level of prosperity, at a lower or higher level. At the same time, the reaction (respectful, condescending, admiring, envious) does not depend on income, but on the person himself.
Thus, a photo of this kind is a public mark of his status or involvement in it.
Do not forget about the exceptions, when the purpose of the photo was not a demonstration of the subject of possession, but the emotions that it brought. And sharing your emotions is one of the needs of a healthy person.
The crowd effect plays a cruel joke on us: many girls take selfies with flowers, the rest also want to, because they are "no worse than this one." The same theme with pictures of freshly bought sneakers or with food. It is difficult to accurately assess the intelligence of such users. Fuck you understand, the photo was taken in honor of a long-awaited gift from a loved one to annoy her friends, or because this is her favorite variety of roses ..
For such individuals, there is even a business: renting bouquets and similar nonsense just to take a photo. Delirium and more. And even a seemingly stupid business idea brings money
I will join the first answer and answer the second part of the question. Selfies with flowers are connected with the intellectual abilities of people as well as any selfies - in no way
I think these girls need the attention of society, they want everyone to know that they have someone to give these senseless bouquets of dead flowers. In short, for me it is pseudo-rendering.
