Maybe times have changed or the new norm is to not capitalize anything in a sentence, but ...
I have 2 superiors:
one takes the time to say hello, ask/please/thank you in their email when requesting things.
the new superior does not feel the need to address anyone in their email while not bothering with capitalization or something not bothering with spelling.
Is this style of writing new? The heading, the sentences are all in lower case. Their name is capitalized.
