I don't believe I've mistaken anything. This person themselves said that they've seen me post my message to you, therefore they most likely have had an interaction with you.
You could reach into your memory and see what you've done prior.
Or maybe you haven't had an interaction with this person at all.
Either way, there's no mistake. You're welcome to talk to @AshleyGryffindor at your earliest convenience. But I've done my part already. Adiue fair stranger.
