Grandpa Jock's Great War - Part 1

This short story is based on the two main characters in my Gorgeous George children's books series. It is a radical departure from the style of the previous books so any feedback would be appreciated. It's my first time on Wattpad so have I posted enough? If not, how many words should I build up each time.Ultimately it will have approx 4000 words and by published as part of the Gorgeous George short stories - thanks
