Sure, Geminis are masters of communication. They have the gift of gab. They can carry on a meaningful conversation about anything with anyone. But, there are certain things they are downright tired of hearing from other signs.
Don't say these to a Gemini, because while you might get a polite response (Twins have manners, after all), they are probably actually thinking something quite different (I included what I am saying in my head).
"I need to vent." (Again? Really? I am not your therapist!)
"You're such a good listener." (What? Are you still talking?)
"We need to talk." (Ugh.)
"Sometimes you're like two different people." (Yep, I am the sign of the TWINS!)
"Just make up your mind." (Give me better choices and I will!)
