Ah it's always sad to see them go, I'm sure you had a brilliant time with them...is it your daughter Babs or friends, I seem to have missed what relationship to you.
@happypat Rob is my nephew and Sarah his partner. They live in Western Australia and flew here for a few days before flying to Brisbane for three days and then to the Gold Coast for 3 days and now home in WA. We had a lovely time doing the tourist bit and lots of chat.
