Time to return to elementary school penmanship class son. In cursive the lower-case n has two humps, and the lower-case m has three humps.
You're right, of course, but most people nowadays don't even know how to write cursive, and I'm not used to seeing it anywhere. I guess don't read as well as I write, but it's almost like reading a dead language. No wonder I thought it was right at first, it was right. Still, I messed up, bad, on that one. It looked different when I rotated it 90 degrees clockwise and used it as a background on my phone. I'm looking at it now, and it looks like an "M" on my phone, even though it only has 2 humps. My brain is telling me that's one too many, but I know that it's right. That's really weird. I can read print upside down, and usually sideways without much trouble, but not cursive, and I never knew that until just now.
This still looks like an M to me, but maybe it's just me.
