Signatures

The signature is important as it represents the image that the person likes to project, whereas the main body of text is how the person actually is.

Signature larger than the text and underlined. - The writer likes to appear confident and seeks recognition for their efforts.
Signature smaller than the text. - The writer prefers to keep a low profile and tends to be rather modest.
Watch out for anyone that puts a full-stop at the end as they generally like to have the last word.
