My old person trait is that I think 'ghosting' is completely unacceptable and you owe the other person a face-to-face conversation.
Computers automatically change it?? I see two spaces here In what you wrote. Typically phone and things like word have settings to show double space after period as single or not and some android keyboard apps auto correct spaces. But I hate single space it makes it hard to read. Punctuation and Capitalization it helps the reader.
