I think my OH thought I was having a 'cyber affair', which is actually quite sad as I can't see the point of an affair unless it's with a real person that you can meet and have 'fun' with, so she misjudges me on that point.
She's always thought my friends are a bit 'different' but I think people in the airline industry are 'different' but having met in the flesh one or two of my Pprune friends, she recently passed a comment : "Oh, they actually seem quite normal!"
