Everyone uses little white lies every now and then! Psychologists say harmless white lies can help you protect yourself and avoid conflict.
The important thing is to be clear about when to use them. Sometimes its better to keep certain things to yourself. Even if we say that if you love someone enough you should be able to tell them everything and vice versa, in truth little white lies don't always hurt. In some situations, they're better than telling the honest truth, which can sometimes lead to fireworks!
So don't be afraid of the odd white lie (within reason). Just take care only to use them when you need to.
