Sincerity - that's what really catches me in people. Not money and cars, not show-offs and designer clothes, not a career and not even the level of education, but sincerity. It's just that from such people blows do not fly through the back to the heart. If they hit, then in the eyes, leaving the right to dodge, defend, respond. If they leave, then not tearing the soul to shreds, but explaining the reason. After them, you stay alive.
