Well, I think the photo this week conveys enough silliness to meet the demands of this prompt: Silly. It's a photo of my sister and I taken several years ago when we were on holiday in Belgium and Luxemburg together. We were staying in youth hostels, seeing the sights, and being silly. As we do! Oh, and I am the up-side-downy one!
This is my fourteenth entry for Photo Theme for Thursday. Why not join?
