I forgot my friends birthday. How do I find out when it is without letting them know I forgot it?

YOu could ask their mom or a friend of hers? WAIT... you could say you are making a new address book... give your friend a pre made card with these on it:

1. Name
2. Address
3. Phone number and Cell number
4. Email address
5. Birthdate!!

Try it;) Have your friend fill in the blanks with all their info and wa la!
