once sitting in mke (was abt 45 mins before boarding) i kept feeling someone staring at me,and i looked up and it was some old Arab guy, so i stare back. eventually he breaks eye contact, so i go back to minding my own business, then when i feel it again i stare back (if he can stare so can i) this goes on and off till they announce priority boarding, so i go to my seat. the plane starts filling up and i see the Arab fellow and his wife are on my flight. i go back to my own business, and then i notice, hes heading right to me. turns out we sat next to each other and then proceeded to talk about; Arabs, Jews and America, just what i wanted
