My sister turned up today out of the blue and asked dd if she would like to go into town shopping for an hour and they could change 2 skirts my sis had bought for dd for her birthday a month ago. I agreed for an hour as we had things planned. That was 11 this morning.
45 minutes ago I rang my sister to ask where dd was - they were just in Starbucks having a drink and she would drop her back in 10 mins! It also turns out that her friend had asked her to babysit her dds (10 and 12) so my sis thought it would be easier to have my dd to entertain them too - hence out for the day shopping.
Still not back and I am fuming!
