What personality trait in people raises a red flag with you?

The trait that raises red flag – or rather that i personally want the other to work upon – is when the person tries to hide feelings when they simply can’t.
For them my simple suggestion is —
You just learn to express yourself the nature πΏπ express itself in the form of season, the flower πΊπ»πΉπ·, cute little insects, and may be many other ways.
Once you began expressing yourself trust me you will become one with the nature πΏπand will be able to feel the world itself……..
