When I was 17, I went camping at a beach one day, and decided to make a sand throne, to relax in, except... it wasn't made entirely of sand, because it would collapse the moment I sat on it. So, I gathered some large stones nearby, arranged them neatly to form a chair, and then covered it with sand to even out the gaps so that it would be comfortable to sit in.

After 2 hours of toiling under the hot sun, the job was done, and I sat in my throne with a great sense of fulfilment. After a while, I retreated back to my tent nearby to rest.

As I stared out of my tent to enjoy the view of the beach and admire my handiwork, a young boy, around 10 of age, went to my throne and walked around it, inspecting it curiously. For a moment, I thought he was going to sit on it. But then, a mischievous glint shone in his eye and he backed away from it a few steps. Then, he dashed and swung a mighty kick! And... collapsed, clasping his foot and crying for his mom.

I stayed in my tent, with tears in my eyes trying to hold back the laughter, thinking "Served you right! ". It wasn't intentional, but making a "sand" structure with stones was definitely the most satisfying passive aggressive thing I did to a troll who goes around kicking sand structures.
