If you were physically incapable of lying, how would you respond to the question: “what is your toxic trait?”

i'm very nice to people which makes them think they are developing something with me but really i am as friendly with friends or strangers, i confide in absolutely anyone who happens to be in front of me when i need to get something off my chest. i can see someone every day for years and over night change my habits and stop seeing them. my ability to create deep lasting relationship is pretty bad and people who invest energy in becoming close to because i seem so kind and warm discover that i am just a nice person with little attachment to specific people. this is why i like being here, i can just say what i want to say to whoever feels like reading it or respond to it
