..Because you think you can find it without looking.
Imagine yourself with a group of friends sitting at a coffee shop, discussing some philosophical ideas, or maybe just talking about how the guy you have a crush on completely ignored you today. Thinking that you are too cool for coffee, you decided to go for a lemonade instead, just to stand out.
Suddenly, the conversation gets good. Eyes are directly on the person speaking. But then, someone reaches for their coffee cup and takes a sip. You see, a sip is one of those things that people follow naturally when we see others doing it. Sort like yawning, or the likeliness to cross the street last minute if we see someone else do it first. I see it all the time when the professor is about to end a lecture, and there is always that one person who starts shuffling papers before everyone else.. sometimes even extra loud, just to trigger others to look at the clock and start putting their things away. This is serious stuff, people.. I’m actually having a serious discussion about this as I type. But anyway, just as since everyone is reaching for their coffee cup, you reach for your lemonade. Nobody looks down at their cups, so naturally (just found out the term for such action is imitative impulse), you don’t either. It wouldn’t be a big deal.. but you’re using a straw.
You must sit there, moving the cup around to try to blindly aim the straw into your mouth. Or you might even do it the other way around (by moving your mouth around in order to find the straw), which isn’t any better; you’ll end up looking like a cow trying to eat invisible grass. Where is the darn thing?!
Finally, you give up and look down. Ah, there it is.
Sip. . . ah.. kward.
