I read this on Rabbi Andy Bachman’s blog. It is a letter from the Park Slope chapter of Hadassah. The woman in need of blood is Andy’s aunt. You can get more information on Rabbi Andy’s blog.

Dear Friends,

I know you are all used to being asked to reach
for your checkbooks for donations, but today I have a request that
won’t cost you a penny.

A woman from our Chapter, is
going into Sloan-Kettering for transfusions tomorrow. She will need
blood for surgery in the very near future after that, once her counts
go up. I am asking for blood to be donated specifically for her, Type
A+.

Vouchers for parking in Memorial Sloan-Kettering’s parking garage are available to donors at the time of donation.

If you can, please forward this email to whoever you feel may be able to help.
