Sometimes you may need to say something in Spanish and not know how. Take a deep breath, and find the phrase you are looking for on your yellow sheet. It may not be the exact sentence you want, but if its close, I will understand.
Example: You want to say: Its so hot in here. Look on the yellow sheet on the front. ¿Me dejas abrir la ventana? Is this the same? No. Does it convey the same idea? Yes. Will I understand you and get the idea? Yes.
