W: Me relax??? That's funny. The only time u have known me to relax is when we were on vacation. That's what I need... A vacation
I could validate with "sounds like you need a vacation" lol
Validation is about getting to the emotions, getting the other person to open up about how something makes them feel. So a validating response might be "sounds like you're frustrated that you can't take a vacation and relax, is that how it makes you feel?" But keep in mind that you don't have to validate everything she says, it's mainly when she's opening up about emotions/ feelings that you should try to validate. If you see her use words like frustrated, angry, mad, sad, etc. then that's a good opportunity to validate.
