Today I watched the Amerian 71 golden globe award, when woody allen was awarded, his friend danne keyton took the award for him and gave a wonderful speech for him. in her speech, she said "It's hard for me to wrap my mind around the fact that ..." I cannot understand "wrap my mind around ..." and I can not look it up in dictionaries because no explanation of the expression was included. So, what does it mean? and can you give me one or two more example sentences containing this pharase?
Thanks a million!
