Their smile doesn’t reach their eyes
People might be smiling back at you, but it doesn’t mean they like you. This is especially valid when the smile doesn’t reach their eyes. If someone sees you as rude and hard to be around, good manners and decency might prevent them from saying it to your face. However, if you pay attention to the way they smile during your interaction, you’ll know exactly what they think of you, says Lynell Ross, founder of Zivadream.
When someone truly smiles, their “eyes are sparkling and crinkled in at the corners,” says Ross. If someone puts on a fake smile, you’ll see that the corners of their mouth are turned up but their eyes are expressionless and impassive.
