I have (or HAD!) a really close relationship with my sister (we are in our 50s). She left the UK to go and work overseas about a year and a bit ago. We had a really close relationship but since she left she's been weird. Spoiling for a fight every time she phones. Very critical To the point that I don't enjoy speaking to her on the phone because there are so many misunderstandings. This evening she called me and I was conscious that she was spoiling for a fight. I was very accommodating but oh dear. I'm worried. What is going on because this isn't like her at all?
