Does anyone else have an overexplainer in their life? This is the kind of person who writes an email with exhaustive, boring detail. When you reply (out of politeness and nothing else), they write another email which is a virtual duplicate of the first. They also say, "See previous email" in case you missed reading the exact same thing.
These tend to be the same people who use voicemail instead of texting, and their voicemails are always unintelligible.
