Here is what  to do:
Get a red envelope. You can buy them at Kinkos or at party supply stores.  Or you can go to a greeting card store like Hallmark and ask them if they have any extra envelopes.  They usually have a huge stash that they are willing to give away or sell cheaply.  That's what we did! On the front, address it to:

President Barack Obama
The White House
1600 Pennsylvania Avenue NW
Washington , DC 20500-0001

On the back, write the following message:
This envelope represents one child who died in an abortion. It is empty because that life was unable to offer anything to the world. Responsibility begins with conception.

Put a stamp on it, drop it in the mail, and send it on March 31st. Make sure you put your return address on it or the post office will not deliver it to the White House. Then tell everyone you know about this website and encourage them to do the same. Time is running out. It is our hope that 50 million red envelopes, one for every child who died before having a chance to live, will be sent to Obama. Maybe it will change the heart of the President.
