A year ago, I realized that I can actually detect when I'm in the presence of my dual by my behavior. I subconsciously become very emotionally protective of them. I verbally attack others who I perceive are being rude, offensive or taking jabs at the SLE. I don't act this way towards anyone else, not even myself most times. For the longest I didn't realize I did this. Looking back, I was that way towards my oldest brother when we were kids. The first time I hung out with both my cousin and her husband, I became instantly protective of him. She's an EIE an her immediate family has made fun of him not having a certain job or education. She told me they would argue because he didn't understand why she never stood up for him. Before I met him, I was indifferent of her family's treatment, so the instant feeling of defensiveness over him was puzzling.

Has anyone noticed a behavior or telltale sign when around a dual?
