There should be a semicolon punctuation for exclamation and question marks.
(self.showerthoughts)
A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Italics
Have you tried handwriting italics? It's not fun.
That's when you underline.
And if you're using software that doesn't support formatting?
You just said you were handwriting.
Emphasis isn't always possible with every utility, but a simple Unicode addition would work well for a variety of software, as well as be easy and readable on paper compared to underlines (especially if there're words below). It's also more accessible if you can't draw straight lines to save your life. Like me.
Switch from block letters to cursive, or vice versa. Or all capitals. Anything that shows a difference.
