I've got "Sarah" that I'm dangling by a text thread.
Last spring she wants her windows doing - I go through the spiel - every other month, no doorstep cancellations, regular through winter. She agrees.
Last April done, last June done, last August done, last October done.
Sarah by Text "can you leave it to February?"
Me "we agreed regular two monthly so not really"
Sarah "we're having work done in December so can you make an exception?
Soft me "ok"
Sarah (late January) "hi it's Sarah, can you leave it until April?"
Me (who's dumped her but not told her) "thanks for the message"
Sarah three days ago "can you do them before easter?"
Me - no reply
Sarah one day ago "can you let me know when so I can leave the gate unlocked?"
Me - no reply
Will I get a text tomorrow? If so I will let you know my reply.
