My friend Michelle is blind, but you’d never know it. She makes such good use of her other   36   , including her “sixth sense”, that she rarely gives the impression she’s   37 anything.
Michelle looks after her children pretty much like the rest of us,   38  that she doesn’t push too hard on them,   39  really benefit a lot from her relaxed attitude. She knows when to clean the house. She moves around so fast that often   40  don’t realize she’s blind.
I  41 this the first time after my six-year-old daughter, Kayla, went to play there. When Kayla came home, she was very   42 about her day. She told me they had baked cookies, played games and done art projects. But she was   43 excited about her finger-painting project.
“Mom, guess what?” said Kayla, all smiles. "I learned how to   44 colors today! Blue and red make purple, and yellow and blue make green! And Michelle   45  with us.

When I told her, she was   51  for a moment. At first, she didn’t believe me. “But Mommy, Michelle knew exactly what was in my picture!” Kayla   52 . And I knew my child was   53  because Michelle had listened to Kayla describe her artwork. Michelle had also heard Kayla's   54  in her work,
We were silent for a minute. Then Kayla said slowly, “You know, Mommy, Michelle really did ‘see’ my picture. She just used my   55 .”
Indeed, she uses a special type of “vision” that all mothers have.
