How's your day going so far?

I try, I really do, but sometimes it's difficult. Cynicism tends to run in my family, so rather than fight an uphill battle, I've decided to embrace my cynicism, at least temporarily.
I realize that certain pleasantries are essential in keeping a civilized society functional. However, I also believe that conditions have gotten to the point where I feel compelled to analyze a few of these bromides to provide myself some clarity. Here are some examples:

What bank teller says: "So how's your day going?"
What bank teller means: "I need to know your mental state, so I can decide whether or not to access the exploding dye packs."

What guy at work says: "You look tired."
What guy at work means: "You look like you slept in a tub filled with gravel."

What woman at work says: "I love your new haircut. It's so cute."
What woman at work means: "Okay, it's going to take a little while to get used to working with Kate Gosselin."

What IT person at work says, in an email: "Thanks in advance for your cooperation in implementing the new system."
What IT person at work means, in an email: "Do this. You need to do this."

What co-worker says: "Your lunch smells great. What kind of fish is that?"
What co-worker means: "The stench of that rotten sea flesh gives me unbridled nausea."

What woman at park says: "Your son is so energetic. I love it."
What woman at park means: "Your son begs for that medication they administer as step one of three, during lethal injections."

What checker at Target says: "Have a great day."
What checker at Target means: "Mmm... ten more minutes until five-dollar footlong time."

What person you run into downtown says: "We should get together sometime."
What person you run into downtown means: "I'd rather eat roadkill."

I know that people can be, and are, sincere and genuine in their statements 99.9% of the time, and I realize these musings are a bit negative. For that I apologize in advance. Have a great day.
