I Am Not The One
Consider this a public service announcement. A preventive measure. A warning label on a human being. "I am not the one" is what you say—or wear—when you need people to understand, before they even think about trying something, that you are not the person to test. Not today. Not tomorrow. Not any day. It's not confrontational because it's not a response to anything—it's a preemptive statement of fact. You're not inviting conflict; you're preventing it by being absolutely clear about who you are and what you won't tolerate. Some people need to know upfront. This lets them know.
