You always nervously anticipate a beep, whenever you walk through a metal detector in the airport, even though you don't have any metal or weapons on you, amirite?

That's why I'm not too fond of going through those xD

I also get nervous when i get in/out stores

I used to whenever I walked out of my high school's library, thank goodness it wore off. It don't even notice it anymore when it comes to libraries and stores.

Yeah, that's happened to me before.
But it was my belt so I had to walk to the other side holding my pants so they don't fall down. :/
