How wet is too wet?

On Saturday we had a big flood.  We had to go to the cafe because it flooded under the back door.That was not very good.   We tried to block up the door but that did not work very well, so we got dad out the back to unclog the drain. We had to stay in the car because the rain was getting the very bad. Dads feet were very wet. We had to stay dry for the rest of the night.
