We were shocked earlier in the week to discover that our kids did not even know what a double-decker bus was. None of them remembered having been on one. It's possible that at least one of them never had.
Lunch was great. A chance to catch up with friends in a vegetarian cafe with a large vegan (i.e. dairy-free) and gluten-free menu. It could have been made for us (give or take some meat).
And then it was back on the bus.
