The photo shows a tweet in Turkish. The tweet's author, Nevîşahsınamünhasır, is expressing surprise and a bit of self-deprecating humor. She's saying that she learned that the chestnut vendors in Taksim Square are generally not police officers, but vendors. Previously, she had admired them (takdirle karşılardım), believing them to be police officers. The joke lies in the contrast between her previous belief and the reality. The humor comes from the implication that she was naive (saflık) and foolish (salaklıkla) in thinking they were police officers, and that this "naivety" somehow suited her well up to that point in her life. The phrase "iyi geldim çok güzel geldim" (I feel good, it suits me well) further emphasizes this self-deprecating tone. In short, the tweet is a lighthearted confession of a prior misperception, highlighting the contrast between initial assumption and the truth, wrapped in a self-deprecating, humorous way.
