An old three letter phrase lots of students write in school yearbooks all over America. Students originally thought that it seems nice to say "keep in touch," just because the majority of people separate off to different colleges
after high school. Thus, people figured that it will be a nice little lasting word, just to be polite, and stay friends, and not be forgotten. But thanks to a little invention in 2004 called facebook, there seems to be an excuse for those people with a "keep in touch" in their
yearbook, to actually keep in touch. This is commonly referred to as
the Keep In Touch Paradox, by students years later. Some girls may have written the abbreviation in the yearbook as
K.I.T., which is just a fast way to write keep in touch. That would be like saying
thanx instead of thank you.
