Impromptu day out

Had an impromptu day out with friend's and their kids - went from a trip to the park to a full outing with all 7 kids to the railway museum, via a "bendy bus". Kids had a great time, we were exhausted, but congratulating ourselves on being out and about with so many children. Until we bumped into another friend, single handedly managing a day out with her 5 kids. I think she's secretly Wonder Woman, it's the only possible explanation.
