We may feel stressed when we feel things are being taken from us. This may include opportunities to go out or the right to use our own space as we wish.
Being assertive is saying how we feel without hurting the other person's feelings.
We say:
"I feel … when …"
"I would like to … instead."
We need to avoid speaking aggressively. Saying, "I hate you because you won't let me go out" will upset the other person and make the argument worse.
