Aack, airports make me nervous. Just being in a place full of people is enough, but when the employees are watching people it's worse. Seriously, I get weird looks sometimes for being so jittery, and I just look like a timid teenager! Excessive paranoia... I would probably never take my laptop with me for fear they would search and/or confiscate it.
My mother is always stopped when my family goes to airports. We assume it's because she looks vaguely Middle-Eastern, though she is Hispanic. Racial profiling is annoying.
