How do you represent $\Im$ and $\Re$ on paper?

Question

Do you draw $\Im$ and $\Re$ just like they are or you write $\mathtt {Im}$ and $\mathtt{Re}$?

Answer 1

Due to my nearly unreadable handwriting, I prefer Im and Re instead of the calligraphic symbols, as noone would be able to read them. I've never seen anyone use the calligraphic symbols in real life either.

Answer 2

I personally write Re and Im on my preprints, too. It seems to me that Re $z$ is much more elegant than $\Re z$.
