完形填空

My mother and I started our morning by rushing into the local grocery store. I waited in line at the Starbucks counter while she        around to pick up a few things.
As I was        there I noticed an elderly woman, wearing layers (层)        layers of old torn clothing, moving behind me in line.
She had a few toiletries(化妆品)and seemed to want the Starbucks cashier to       since our queue was shorter than the grocery store queues were.
At some point I became       of her moving closer behind me –it was         than I was comfortable with! I instinctively (本能地)      a hand over my purse and drew it closer to me. My fear and imagination raced creating wild         about this homeless woman who might try to          from me.
Then it was my         to order. As the cashier rang up my total I discovered I was 37 cents        . I called to my mother but she is hard of hearing. She asked me to         what I said but she still couldn't          me out.
At that point, a long grey arm, with         in its sleeves,          over from behind me. She laid 37 cents out on the counter, saying, "Here, We all need some        sometimes."
I was         ! Here was a woman who clearly had very little to         and in great need herself. I had judged her         and she had reached out, voluntarily, to help me!
What an amazing gift and lesson this woman gave me about         others. Thank You, God!!
