So I have this 'friend'. She never waits to be invited but just announces she wants to visit (usually stays one night). I can put her off but she will go on about it so I'm forced either to say no I don't want you to visit (I've never had the guts) or just capitulate (I always do). Then the moment you've agreed a weekend she starts becoming difficult. The traffic is too bad/too hot for the dog so she wants to come midweek (I work full time and am single mother of two secondary school children, plus the house is small, only 2 bedrooms). She informs me that she will need to work during the evening when she visits (we both work from home). I have told her that I have to take my DS to his dad's on that evening which will take 2 or 3 hours, but that didn't put her off. Why is she like this? Is it (a) she is just plain weird; (b) it's a power play, 'my time is more valuable than yours' - I've noticed when she starts working if I get on with my own stuff rather than sitting there like a lemon she promptly snaps shut her laptop; (c) she's an unhappy person who feels a bit better if she's messing someone else around??
