Wing Dings.

Because you wouldn't be able to read it.

My handwriting is publicly available as a font I made from scratch as a teenager, so definitely that one.

Wingdings. My handwriting is really bad

If I'm being aspirational I'd probably identify most with Courier New... if I'm being honest...

I haven't had to seriously handwrite anything in the past two decades and my handwriting probably peaked when I was 7.

• For block writing: Google Fonts — Architect's Daughter, but a bit more narrow. I also tend not to use lowercase in block writing.
• For cursive: Google Fonts — Hurricane, a way messier "variant" of that.

I don't know that my handwriting is super consistent, but I think it kind of looks like Sour Gummy. Some individual characters maybe not so much, but I like the overall aesthetic.

I don't think I can answer since equating to a font would indicate of consistency or repeatability that doesn't exist.

I'm in my 40's and I still can't decide if I prefer writing a 7 with the crossbar though it of not. Of if I should draw a 4 like a triangle on a stick or a poorly made box.

Legible

Mine is probably closer to comic sans than anything else I can think of.

I'm a right hander whose writing slants left. There are basically no fonts that slant left, so I guess, none?

Imperfectly scripted

What an interesting question! I would have to say the closest is Playwrite Australia, due to my habit of combining cursive and print.

Monaco, I guess?
