A man has just been to install my new shower. First he asked if it was OK to put the bar at the same height or did I have a tall partner, then he said my cooking smelled nice, made some friendly comments about how it must be hard on my own with DS, then he managed to spray himself with the shower while testing it and get soaked, and finally he restapled the horrible bit of carpet back to the side of the bath where DS had ripped it off, just as a favour without me asking or even mentioning.
Then when he left he said "You've got my number, haven't you? ...In case you have any problems." He didn't wink but there was a definite twinkle in his eye.
