I Already Told You, I’m Not Wendy!
This is rare but it does happen. A stranger accidentally sends you a text message that’s meant for someone else. You subtly tell her that it’s the wrong number but she still sends more messages. You now tell her directly but she persists as if you haven’t told her anything.
You even text the back pictures to show that you can’t be Wendy under any circumstances but she’s relentless. There’s simply no way of handling this other than calling this sender right away if possible and alerting her of the situation. They might be sending you crucial and even life-saving messages that are needed elsewhere.
