We are not accountable or responsible for others' moods, emotions, conditions or point of views.
They choose how they are feeling or responding to you and your responsibility is to choose what is best for you. We can of course have 'off' days but the key is not to let it ruin your peace of mind or cause you to be offensive or judge yourself in negative ways.
Let it go.
Don't allow it to over run your day.
Ask Archangel Michael to detach all the negativity from the situation, or other's words and hand the situation over to the angels so they can help the individual or situation result in the best way for all involved.
