Where the phrase comes from · Card no. 4007
From the swimming pool. Once pools became common in American towns in the early 1900s, the deep end was the part you had to be able to swim to reach, so going off it meant acting without the ability to cope with what came next.
No such place exists, which has never stopped anyone from going. Every card here is an original painting of a phrase, free to send by email or by link.
