"but...."

One of my students was telling me something that I quite honestly wasn't giving 100% of my attention to. I'm sure my mind was in 5 different places at that moment. I heard her pause in what she was telling me so I assumed she was finished. I responded with a universal response of "wow, that's great." I focused my attention elsewhere for a few minutes only to find the student trying to get my attention again. She said to me, "Mrs. Vining, you did not let me tell you the BUT part of my story!"
