This text introduces the "Let Them" theory, arguing that most adults possess the emotional maturity of eight-year-olds and are incapable of effectively managing their feelings. The author posits that rather than attempting to fix others' emotional outbursts, one should "Let Them" experience their emotions, thereby freeing oneself from the burden of managing their reactions. This approach, however, requires self-awareness and the ability to manage one's own emotions, a skill the author advocates for cultivating through self-compassion and understanding. The text offers strategies for applying this theory both to others' and one's own emotional responses, emphasising the importance of self-regulation and healthy emotional processing. Ultimately, it promotes personal responsibility for one's emotional well-being and the establishment of healthy boundaries.
