Meaning of an invite to try Birthdays on Facebook?

[sweetsmiles]

I added a girl from my school as a friend on Facebook, and she's been "inviting me to try Birthdays"...

The first time she sent me one, I asked my best friend, and she told me not to worry about it. Today, she sent me another one, so I started wondering if I should do something.
Also, the girl I'm talking about isn't really my friend at all, and I've never even talked to her before.

Does she want me to wish her a happy birthday (her birthday was last week)? Or is it just a friendly request to try out birthdays?

Most likely "Birthdays" is one of those apps that when you start it up, it says "Invite your Friends!" and gives you all of your friends. She presses enter, blam. All her friends = annoyed. It's nothing personal.

Its Just A App Where you Add it and It Sends out Cards And Birthday Stuff on There Birthday If you Have it People Who Use the App May Send you Something Special if you Want to Try it out Go Ahead Other Wise Just Ignore the Request and Delete it
