I don't remember if I ever mentioned this before, but for over 20 years now, I've been getting someone else's e-mails. I don't think it's a malicious spammer, I think it's someone accidentally always entering in my e-mail address instead of theirs. This has been happening since as long as I've had my main Gmail* address, so since... 2004? When did Gmail start?
*please do not use this as an opportunity to tell me to migrate off of Gmail/Google products, I already know okay
