It often surprises me how unwilling people can be to accept that they have got a wrong number when they make a phone call.  It seems that applies to text messages too.  I got one signed Charlotte that clearly was not for me and out of the kindness of my heart I replied "wrong number".

Instead of "sorry" or "thanks for letting me know that I made a booboo" I got "It's me Charlotte, I have got you (sic) chair darling x" to which I felt obliged to make a more forceful response clarifying the situation.

"I do not know any Charlotte.  I am not expecting a chair. I am not your darling. You have got the wrong number."

Silence has reigned since.
