We handed our final contribution to a small girl and then immediately（39）Cback in the opposite direction for home．（40）C，the light caught us again and we were stopped at the same crossing where this small girl stood．I was（41）Band didn't know quite how to behave．
She made her way to our car，"No one has ever done（42）Clike this for me before，"she said with（43）A．Feeling uneasy，and wanting to move the conversation along，I asked，"So，（44）Ddo you think you'll eat your lunch？"
She just looked at me with her huge，tired brown eyes and said，"Sir，I'm not going to eat this lunch．"I was（45）B，but before I could say anything，she continued，"You see，I have a younger sister at home and she just loves McDonald's，but I don't have the（46）C．But you know what…tonight she is going to have McDonald's!"
I don't know if the kids（47）Cthe tears in my eyes．So many times I had questioned whether our acts of kindness were too（48）Bto really make a difference（49）D．at that moment，I recognized the（50）Dof Mother Teresa's words："We cannot do great things-only small things with great love．"
