"I will let you know by email if Mrs X will drop by at your place Monday morning at 9."
Sure, no email. How should I interpret that. Had Mrs X been reached, was she on her way, but had Mrs Y forgotten to mail me?Had Mrs X not been contacted?
There I was, waiting.
Did write an email this morning at 8, to ask what to expect. No answer on that. And no Mrs X at my doorstep at 9. 9.15 I decided she probably would not come.
