     My brotherinlaw opened the drawer of my sister's cupboard and took out a package.He said, "This is

a new silk slip (衬裙). Jane bought it in New York nine years ago.She never wore it.She was saving it for a special occasion.I guess this is the occasion."

     It was an exquisite (精美的) handmade silk slip.The price tag on it was still attached.

     He took the slip from me and put it on the bed, with the other clothes we were taking to the mortician (殡仪员). His hands lingered on the soft material for a moment, and then he shut the drawer and turned

to me, "Don't ever save anything for a special occasion.Every day you're alive is a special occasion."

     His words have changed my mind.I'm spending more time with my family and less time on meetings.

I'm trying to recognize these moments now and cherish them.I'm not saving anything.I wear my good skirt

to the market if I feel like it.I can pay $28.49 for a small bag of groceries.I'm not saving my good perfume

for special parties.If something is worth seeing, hearing or doing, I want to see, hear and do it now.

"Someday"_has_disappeared in_my vocabulary.

     I'm not sure what Jane would have done if she had known she'd not be here for the tomorrow.I'm

guessing Jane would have called family members and a few close friends.She might have apologized to

her former friends for their past quarrels.She'd have gone out for a Chinese dinner, her favorite food.

     I'm trying hard not to put off, hold back, or save anything that would add laughter to our lives.Every

morning I open my eyes, I tell myself that every day, every minute, every breath is a gift.
