Gemini With Sagittarius:

They both need to have a lot of personal freedom but in different ways. Sagittarius must always feel that he/she is free and can do anything he/she pleases, whereas Gemini will only want to do the forbidden, or restricted. Although sometimes a nagger, Sagittarius cannot abide anyone nagging him/her, which will give the feel of restricting his/her personal freedom; this will eventually drive Sagittarius away.
