Pathological Liar

I was going about as usual and from nowhere you came into my life. Said you were a pathological liar and I don't need to know your name because it changes day by day. I ask you since you're a pathological liar how do I know you're telling me the truth. You said labels are just ways of generalizing the unique. So I didn't ask anymore and we went on about our days. One day you were not where you usually are and I began to wonder. I ran into you later and asked where you were. You say you've been there all along. And I ask why I should believe you since you're a pathological liar. I obviously didn't see you. You said "because I'm no liar" and that's the last time I saw you.
