Allow people to have whatever mood they choose, it's not your responsibility to manage. Don't allow those moods to seep into you and start rearranging your peace. Because sometimes moods aren't just moods, they're tools used to manipulate and quietly control. To guilt you, confuse you, and make you question things you were once sure about. Getting affected is like handing over your stability and sanity without even realizing it. They may think they're smart, playing their little emotional chess games with confidence. But you're smarter, you just don't feel the need to announce it every time. They expose themselves eventually, because cleverness with ego always leaks through cracks. Nothing looks more foolish than trying too hard to prove you're the smartest person around.
