Thank you both very much. I keep looking up grammar/capitalization rules and it's starting to muddle my brain. I did try to drive while using my poetic license once, but I ended up in the ditch, so I leave that at home now.
I know you're supposed to capitalize a title when it takes the place of a name, like: "Hello, Doctor." But I mistakingly thought it applied to names of affection too. I will go through and correct those instances. *long drawn out whine*
On this, I believe the comma needs to be at: "Greetings, Liselle Human"
For this reason: "Use commas to set off the name or title of a person being spoken to directly.
Examples: For further information, Mr. Lombardo, please contact our regional office in Duluth. Vicky, do you have a copy of the company’s most recent annual report? I very much appreciate your many helpful suggestions, Professor."
