He was soon home, his Gran in a dressing gown cooking, all appeared well with the domestic world.“Hi Gran, how`s you?” she grinned, “OK… just ... bit behind, what homework?” “history and I had geography, but I managed that in the library so just a bit on the Vikings and I`m all yours, it`s about longboats so it shouldn’t take long.
