There are so many times when a completely blindsided unexpected question may be asked and I do not have a response. When my guard is not up and my response is weak or stupid. Following that I tend to overthink the situation and feel embarrassed not because I said something stupid but more that I wish I could have responded better. I hope what I am trying to say makes sense. Can someone point me in the direction of a good book to read to combat this type of situation?
