The note-

Have you ever needed to send a note to your child's teacher excusing a lateness or absence? If you have no children, have you ever needed to send a "real" note to a co-worker requesting something?

What did the note look like? Was it a piece of paper torn off the weekly shopping list, a sticky note or maybe even a piece of scrap paper and jotted down haphazardly?

Any note you send to someone not only contains the specific message but  is also a reflection what you think of them.

If your child requests a note for the teacher and you take the effort to write a note on a proper piece of paper with the teacher's name "Mr. Jones" and not "to the math teacher", then you put it in an envelope and address it to the teacher it becomes an unwritten message to the teacher that you value his effort and it shows the child that you value the teacher to send a proper letter.

Personally, when I have to sign a permission slip for a class trip, almost always add a note to the bottom of the page "have a nice time", "watch out for wandering monkeys" (for the zoo), or something else that shows I value the trip and the efforts of  the school to arrange the class trip.

If you need to send a note to a co-worker or client, a handwritten note on a nice piece of paper is a reflection of what you want your relationship to be with them. Even if it just says "With Compliments from Judy"  a note like this means a lot to them and it will give them a good impression of you.
