A thunderstorm and a tent

When I was young, my friends and I had a tradition of going to the forest with tents on the first weekend of summer.
Once, while camping, we were caught in a thunderstorm. 
We quickly hid in the tent and thought everything was under control. But water started seeping through the bottom. 
I, like a real hero, decided to dig a small ditch around the tent to drain the water. As a result, not only did I get soaked to the skin, but I dug the ditch on the wrong side - the water flowed right under the tent. 
As a result, all the things are wet, we are wet. the camping ended quickly
My friends still remember my “rescue plan”.
