Blank Stares Don't Count
Today is the day to fill in the _____. Fill in the Blank Day originated with the TV game show The Match Game. The questions posed to the contestants often were in the fill in the blank format.
Eventually, someone saw the need to create a full day for this activity. And with good reason. There are so many places you can fill in blanks these days.
When shopping, you still (for some silly reason) often have to fill in the blank with your signature (or a reasonable facsimile) on the touchpad in the checkout line. You probably can't recognize your signature after you're done attempting to write it there, and neither can anyone else, but that's okay because no one else will ever have reason to read it. It's a formality that's past its time.
More reasonable places to fill in the blank with your signature are on paper documents. Some of these are legitimate, others are questionable. Legal documents signed before a notary public or a lawyer are fine. Signing the bill at a restaurant is about as useful as the electronic version mentioned above.
If you never learn to write in the cursive style, do you still have a signature? I suppose your printed name becomes your signature. I've heard tell of people who couldn't read or write at all using an X as their signature. I'm not sure how legal that is when it comes right down to it. I guess as long as whatever you sign can later be identified as having been written by you that makes it okay.
I've mostly covered signatures in blanks here, but there are dozens of other things you can fill in the blank with too. Maybe you can think about them for next year.
