There are over 6 billion people living on earth and each of them is unique. They vary in race, religion, political beliefs, and cultural differences, but I believe we can basically divide the human race into two separate groups. Those who cross their sevens and those who don't. I dedicate this post to those who do (judging from how long it took me to find a picture of a crossed seven on the Internet I'm pretty sure that group is in the minority).
I'm a 7 crosser and I think I started when I was living in Europe as a kid. I remember my teacher was a stern woman who wore a white lab coat who walked up and down the isles as we worked on math. The Austrian kids were doing pre-calculus in third grade but I was still trying to figure out long division. (Don't feel bad I wasted them all in P.E.) Anyway to fit in with the other kids I started crossing my 7's and I guess it just stuck.
This habit may have been reinforced if I mistook a 7 for a 1 and had such a traumatic experience that I swore that would never happen again, but if that did happen I'm not sure because I probably suppressed the memory. Anyway I really struggle when I see a regular 7 because I want to cross it. It even pains me to write this post with a keyboard that will not type a 7 the way I like it. I also cross my Zs so they don't get mistaken for a number 2. I know most people wouldn't usually confuse the two but I work with Vin numbers everyday.
I feel a need to apologize for the lameness of this post, but you have to take into account the boring nature of the subject matter. Anyway if you don't cross your sevens then I challenge you to just try it once to see if you like it or not. At least I'm not trying to promote making a smiley face out of the dot on the letter i.
