Someone will be standing in your way whatever you are trying to do today, but stay calm and do not fight.
Whatever you are trying to do today someone will be standing in your way at every turn. This is going to be very frustrating for you, but try not to let it get to you. If you try to fight against this you are only going to cause more tension and conflict between you and the other person. Instead, talk to them calmly and explain your position. If you cant agree, leave it till later when things are quieter.
