Family grrrrrrrrrrrrr

On the weekend I met a guy name Andrew and tonight we were going to catch up but my sister who went down to ACT to see the boyfriend for the weekend WAS flying back in today at 7am, But miss her flight and will not be flying back until 7pm tonight.
AND
My mum phone last night and told me that I have to keep Friday night free because she is flying up and needs MY car (not my sister car) for the day. Don't get my wrong I love to see my mum but I'm going to be staying with her for awhile when she moves up in two weeks.
