Sister act

Martine came over yesterday and stayed til 7pm. We went for a walk to by the station with the dogs while she was here. Ang woke me just before 6 this morning and I refused to go to the garage for her. Eventually agreed to meet her on the way back so dogs got an early walk. Thankfully both of them pooed after met Ang. Got back and Ang rang and accused me of not giving her the change from her shopping yesterday. She keeps ringing and just rang and said her shopping was over £10 so I couldn't have given her the change. Problem is her shopping was about £8.50 and I know I gave her the coins and a £10 note back. Thoroughly fed up now and it's only 8.15.
