Standing in line . . .

Please tell me that it's not just me. I'm pretty sure I have an invisible sign somewhere on my forehead that only rude people can see. It must say something like "sure, go ahead and cut in front of me, use me as the break in the line to pass through, I'm not really here anyway". I have noticed more often than not that when I stand in line, and it doesn't matter where I am, I'm always the one who people decide to use to cut through the line instead of going around. It happened last night at the mall. It happens everywhere. Seriously, I must look like the nicest person in the line or something. Or maybe I have the aforementioned sign. Who knows, but it's getting old. Those same kinds of people are the ones who will literally walk straight toward me in the grocery store, making me practically leap out of the way to avoid crashing our shopping carts. Am I invisible? Please tell me I'm not alone!
