Not my decision

Adult kids. Oh, man...see if you can identify here. One calls you for your "professional opinion" regarding something medical. (Substitute your own scenario here) You ask a few questions to better assess the situation and their temperature begins to climb. After clarifying what you heard, you then say "if it was me, I would (fill in the blank)". 3...2....1 We have lift off! Because your opinion is NOT what they wanted to hear, despite the fact they know it's probably a wise decision, they get m-a-d. And their mood does not improve when asked "YOU... called ME... right? And you asked for my opinion, correct? Well, here it is. Do what you want." Yah, yah...yah....whatever.
Two hours later, they call again to tell you they are 1) doing what you suggested 2) and still complaining about it, at which point all you can say is "smart idea...glad you are doing it". Click. Then another hour and a half passes, you are in bed reading, and the phone rings, again. This time, they want to give you the blow by blow details... and by now, you are struggling to smother your laughter. They are in full bore poor little me mode and it's all you can do not to hand them a sticker through the phone, for being sooooo big!
In the past, both boys have asked to talk with the nurse part of me and not the mom part---it takes me a second to shift gears, but it works. The nurse part is really fun---you just give them information, and the decision and results are strictly theirs. But the mom part is even more fun. You get to tease them about it afterwards.
