When someone misunderstands you today, be clear in your intentions and be sensitive.
Misunderstandings are likely today and someone in particular will completely misinterpret something you say or how you act. Whatever it is they have not understood the meaning of, it's up to you to set them straight. Do this gently and with sensitivity, as they already have the wrong opinion of you. Do not hold it against them, you have to be clear in your intentions.
