Slow walkers, their friends, and people who don't move

I hate people who walk really slowly or who look all around as they're walking and get in my way. Are you a tourist? Have you never seen a construction site before? Is there something on top of that tall building? Do you like what's in that store window? Maybe you should STOP and move to the SIDE instead of continuing to walk an S-shaped curve in front of me.

Even worse than these meandering lookers are people who know exactly where they're going and simply choose to crawl along in front of me when I'm running for the bus. These are the same people who always give you dirty looks when you pass them, as if they're aware of their grandma speed but feel that you do not have the right to pass them. I always imagine that those are the kind of people who constantly complain about how things have changed since "their day."

At least, to their credit, these people don't see me coming because I come up behind them. But for the love of god, what is wrong with people who walk in packs down the street TOWARDS me and refuse to get out of my way? You know, the family of seven traveling like a street gang and occupying the entire sidewalk, forcing me to step out onto the curb just to continue on my merry way. I'll be damned if I'm gonna get nicked by a speeding car because some waste of air can't bother to observe the coming and going lanes of the sidewalk. My solution: closing my eyes and spinning my arms like a windmill. Then at least if they don't move, I might injure someone.
