Oh, I see. It never occurred to me that someone might be embarrassed about their handwriting. My bad. I'll try to post some of mine tomorrow. But here's an interesting exercise: What do you think someone's handwriting looks like, based on their personality. For example, I picture Nas' handwriting as rounded and bulbous, like a middle school girl's. I bet he'd dot his "i"s with little hearts if he thought he could get away with it. 
Thrash I picture with a sort of jagged scrawl, small letters, widely spaced.
It's not specifically that I'd be embarrassed by it, though I'm sure someone of my mother's or grandmother's generation might think I ought to be (the look on the latter's face when I told her employers would likely not take a handwritten résumé seriously, after she repeatedly insisted that showing off neat handwriting in one was the most important first impression, was priceless). It's more a principle of privacy, combined with more than a little bit of paranoia around the issue Redezra brought up.
I picture both your printing and handwriting (heh, it just occurred to me that growing up, handwriting was seen as a synonym for cursive, to be opposed to printing, whereas now it can be used to include either block print or cursive, opposed to typing) to be impeccably neat, every letter a carbon copy of the other, all evenly-spaced from each other. I imagine your hand is capable of printing in
Helvetica.
Redezra mentioned in both the pens thread and another thread recently where she mentioned how much she depends on computers (can't for the life of me remember where that topic started or what it was otherwise about) that her writing is quite messy, which startled me; I would have otherwise pictured Redezra's writing to be similar to how you described Nas', akin to
French Script MT or
Catholic School Girls BB.
