Really love it when I make mistakes like this. The other day I saw an email from my architect asking if we could meet up at the weekend. I was really puzzled, because there wasn’t a copy of it in my work email, even though it was clearly sent to both my email addresses. I sent a reply to him saying fine let’s do it, and after I clicked send I realised his email was from five months ago.
He still accepted the meeting though, so result!
