He has some of the worst handwriting. I can tell him over and over to write neater and more legible but it really does no good because it always looks like a big jumbled mess when he is done with it. I can read it because he is my kid but sometimes I even have trouble.
I have the same problem.
It is kind of embarrassing when the law partner asks you what you wrote on the document when you are marking it up and you say "I'm not sure. My handwriting is kind of hard to read."
I can generally decipher what I was trying to say, though, so it's usually all good. Sometimes I have to guess, but I'm generally pretty good at reading my own writing.
