Talk about it (and Listen)
Most Relationship problems at home and at work come from not talking things over. If you are feeling uptight about a situation with another then say something. Remain calm and explain how you are FEELING about the person or situation. Then ask for their feedback in how to fix the concern and most importantly LISTEN to what the other is saying. So many relationships are destroyed and so much anxiousness is built from within because people don't talk stuff over. And don't you feel so much lighter when concerning topics are solved.
