Yikes! The worst thing I remember doing was taking my horse to the lake and making her swim.... I would strip off her saddle and hide it in some bushes, then urge her into deeper and deeper water until she started leaping....then swimming. I would hold on tight to her mane and basically float above her, trying to stay over her so when she touched bottom again and started leaping, I would end up on her back and not under her legs.
I did not know how to swim.
The other thing my parents didn't know was that I would ride alone miles into the woods and fields, where humans rarely went, and if I saw an apple tree, I would park that pony under the tree and stand on her back to pick the best apples.
