LOL yeah right!
The person on the other end can still keep what u sent them kinda. It wont be in the same format but its still possible. U just need a second device. If u send something visual like text, pic, document, etc they can "screenshot" it by reading it on one device(ex iPad) while video recording it from another device(ex iPhone) while they read it. Same can b done with anything audio by doing a sound recording.
